[0068] The following section describes the relevant technologies involved in the embodiments of this application:

[0069] • Physical downlink control channel detection:

[0070] Network devices send Downlink Control Information (DCI) to terminal devices. DCI is used for downlink scheduling, such as scheduling the Physical Downlink Shared Channel (PDSCH), or for uplink granting, such as scheduling the Physical Uplink Shared Channel (PUSCH). DCI can also be used to transmit common control information, carried over PDCCH. Network devices configure a search space for terminal devices. Different aggregation levels (ALs) can be configured, and at each AL, the number of candidate PDCCHs the terminal device needs to monitor is configured. Terminal devices need to perform PDCCH detection within the search space. Since the terminal device does not know which resources in the search space the network device will send PDCCHs on, it needs to detect each candidate PDCCH resource in the search space; this process is called blind PDCCH detection. The maximum number of PDCCHs that a terminal device needs to monitor within a time slot is related to the subcarrier spacing. For example, with a subcarrier spacing of 15kHz, the maximum number of PDCCHs that a terminal device needs to monitor within a time slot is 44. Referring to Table 1, when the subcarrier spacing parameter μ takes values ​​of 0, 1, 2, and 3, it corresponds to subcarrier spacings of 15kHz, 30kHz, 60kHz, and 120kHz, respectively.

[0071] Table 1

[0072] In 5G NR systems, DCI uses Polar encoding. Each time the terminal detects PDCCH, it needs to perform decoding, which leads to higher power consumption and increased processing latency.

[0073] A PDCCH's transmission resources can include M1 Control Channel Elements (CCEs), corresponding to different aggregation levels (ALs), for example, M1 = 1, 2, 4, 8, 16, 32. The relationship between aggregation level and the number of CCEs is shown in Table 2 below. Each CCE can include M2 ​​Resource Element Groups (REGs), for example, M2 = 6. One REG corresponds to a Physical Resource Block (PRB) in the frequency domain and an Orthogonal Frequency Division Multiplexing (OFDM) symbol in the time domain. The transmission reliability varies depending on the number of CCEs occupied by the PDCCH; for example, the more CCEs a PDCCH occupies, the higher its transmission reliability.

[0074] Table 2

[0075] • Optimization of terminal device complexity:

[0076] Terminal devices, often simply referred to as terminals, are designed to support extremely high peak data rates. Therefore, the requirements for terminal capabilities are quite high. The LTE standard defines a maximum single-carrier bandwidth of 20MHz, with larger bandwidths achieved through multi-carrier aggregation. 5G NR ultimately defines a maximum carrier bandwidth of 100MHz for frequencies below 6GHz, five times that of LTE, while the maximum carrier bandwidth for millimeter-wave frequencies is 400MHz. The required multiple-input multiple-output (MIMO) antenna configuration for NR has also been further increased. The reference antenna configuration for LTE terminals is one transmit and two receive antennas, while NR Rel-15 (the 15th version) requires two transmit and four receive antennas at frequencies above 2500MHz.

[0077] However, some NR applications do not require such high processing power in terms of capacity and speed. These applications include the Internet of Things (IoT), industrial automation, and wearable devices. These scenarios demand communication hardware with low size and power consumption; lightweight capability is a characteristic of these terminals. Based on this consideration, NR Rel-17 (the 17th version) research introduced a compact terminal standard with reduced capability (RedCap).

[0078] The Compact Terminal standard reduces some mandatory capabilities of NR Rel-15 / Rel-16. Corresponding terminal function groups are defined for these capabilities. The Compact Terminal standard also further optimizes terminal identification, access procedures, and power consumption in measurements to suit relevant application scenarios. This compact terminal design significantly reduces the complexity of terminal hardware and correspondingly reduces power consumption, thus achieving energy savings.

[0079] Before introducing the technical solution of this application, some contents involved in this application will be described first. The following contents are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and all of them fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0080] In some embodiments, the set of transmission resources configured by the network device for the terminal device includes at least two types of transmission resources.

[0081] Optionally, a set of transmission resources includes a first transmission resource and other transmission resources, where the other transmission resources are those other than the first transmission resource. For example, the other transmission resources include a second transmission resource. The first transmission resource is used to transmit first indication information, and the second transmission resource is used for downlink transmission. The transmission content of the downlink transmission (i.e., the downlink transmission content) includes downlink data and / or downlink control information (DCI). The following embodiments primarily illustrate this by citing the inclusion of a second transmission resource among the other transmission resources, but are not limited thereto; for example, the other transmission resources may also include a third transmission resource.

[0082] In this embodiment, the network device configures a first transmission resource and a second transmission resource to the terminal device, and there is an association between the first transmission resource and the second transmission resource. The terminal device can determine the location of the second transmission resource based on the location of the first transmission resource.

[0083] Correspondence between the first transmission resource and the second transmission resource

[0084] In some embodiments, the correspondence may also be referred to as the association.

[0085] In some embodiments, the correspondence between the first transmission resource and the second transmission resource is one-to-one, many-to-one, one-to-many, or many-to-many; wherein, one-to-one means that one first transmission resource corresponds to one second transmission resource, many-to-one means that multiple first transmission resources correspond to the same second transmission resource, one-to-many means that one first transmission resource corresponds to multiple second transmission resources, and many-to-many means that multiple first transmission resources correspond to multiple second transmission resources.

[0086] Optionally, when the correspondence between the first transmission resources and the second transmission resources is many-to-one, at least one of the time-domain resources, frequency-domain resources, or code-domain resources corresponding to the multiple first transmission resources is different. For example, the multiple first transmission resources have the same time-domain resources but different frequency-domain resources; or, the multiple first transmission resources have different time-domain resources but the same frequency-domain resources; or, the multiple first transmission resources have different time-domain resources and different frequency-domain resources; or, the multiple first transmission resources have the same time-domain resources and the same frequency-domain resources, but different code-domain resources. For example, the multiple first transmission resources are located in the same time-domain symbol, but the corresponding PRBs are different; or, the multiple first transmission resources are located in different time-domain symbols, but the same frequency-domain resources; or, the multiple first transmission resources are located in different time-domain symbols, but different frequency-domain resources; or, the multiple first transmission resources are located in the same time-domain symbol, but the same frequency-domain resources, but correspond to different sequences.

[0087] Optionally, when the correspondence between the first and second transmission resources is one-to-many, the multiple second transmission resources have the same time-domain resources but different frequency-domain resources; or, the multiple second transmission resources have different time-domain resources but the same frequency-domain resources; or, the multiple second transmission resources have different time-domain resources and different frequency-domain resources. For example, the multiple second transmission resources are located in the same time-domain symbol, but their corresponding PRBs are different; or, for another example, the multiple second transmission resources have different time-domain resources but the same frequency-domain resources; or, for yet another example, the multiple second transmission resources have different time-domain resources and different frequency-domain resources.

[0088] Optionally, when the correspondence between the first transmission resources and the second transmission resources is many-to-many, if the multiple first transmission resources include M first transmission resources and the multiple second transmission resources include N second transmission resources, then M1 first transmission resources correspond to N1 second transmission resources, where M, M1, N, and N1 are integers, 1≤M1≤M, and 1≤N1≤N.

[0089] Figure 2 illustrates a schematic diagram of the correspondence between transmission resources provided in an exemplary embodiment of this application.

[0090] In Figure 2(a), the first transmission resource and the second transmission resource have a one-to-one correspondence, that is, one first transmission resource corresponds to one second transmission resource; in Figure 2(b), the first transmission resource and the second transmission resource have a many-to-one correspondence, that is, two first transmission resources correspond to the same second transmission resource; in Figure 2(c), the first transmission resource and the second transmission resource have a one-to-many correspondence, that is, one first transmission resource corresponds to two second transmission resources; in Figure 2(d), the first transmission resource and the second transmission resource have a many-to-many correspondence, that is, any one of the two first transmission resources corresponds to both of the two second transmission resources, or, any one of the two first transmission resources corresponds to either of the two second transmission resources.

[0091] Positional relationship between the first transmission resource and the second transmission resource

[0092] In some embodiments, the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the location of the second transmission resource and the location of the first transmission resource based on a communication protocol; or, there is a pre-configured relationship between the location of the second transmission resource and the location of the first transmission resource based on a network.

[0093] By way of example and not limitation, the positional relationship between the first transmission resource and the second transmission resource includes at least one of the following:

[0094] The first transmission resource and the second transmission resource are not adjacent in the time domain; the first transmission resource and the second transmission resource are adjacent in the time domain; the start position of the time domain of the first transmission resource is the same as the start position of the time domain of the second transmission resource; the start position of the frequency domain of the first transmission resource is the same as the start position of the frequency domain of the second transmission resource; the center position of the frequency domain of the first transmission resource is the same as the center position of the frequency domain of the second transmission resource; the end position of the frequency domain of the first transmission resource is the same as the end position of the frequency domain of the second transmission resource.

[0095] The temporal adjacency between the first transmission resource and the second transmission resource means that the temporal end position of the first transmission resource is adjacent to the temporal start position of the second transmission resource.

[0096] Figure 3 illustrates a schematic diagram of the positional relationship between transmission resources provided in an exemplary embodiment of this application.

[0097] In part (a) of Figure 3, the first transmission resource and the second transmission resource are not adjacent in the time domain, and the frequency domain center position of the first transmission resource is the same as that of the second transmission resource.

[0098] In part (b) of Figure 3, the first transmission resource and the second transmission resource are temporally adjacent, and the frequency domain center position of the first transmission resource is the same as that of the second transmission resource.

[0099] In part (c) of Figure 3, the starting position of the time domain of the first transmission resource is the same as the starting position of the time domain of the second transmission resource, and the starting position of the frequency domain of the first transmission resource is the same as the starting position of the frequency domain of the second transmission resource.

[0100] In part (d) of Figure 3, the starting position of the time domain of the first transmission resource is the same as the starting position of the time domain of the second transmission resource, and the center position of the frequency domain of the first transmission resource is the same as the center position of the frequency domain of the second transmission resource.

[0101] In part (e) of Figure 3, the time domain start position of the first transmission resource is the same as the time domain start position of the second transmission resource, and the frequency domain end position of the first transmission resource is the same as the frequency domain end position of the second transmission resource.

[0102] Types of first and second transmission resources

[0103] In some embodiments, the first transmission resource and the second transmission resource are common transmission resources shared by multiple terminal devices; or, the first transmission resource and the second transmission resource are group transmission resources shared by a group of terminal devices; or, the first transmission resource and the second transmission resource are proprietary transmission resources used by a single terminal device.

[0104] In some embodiments, when the first transmission resource and the second transmission resource are common transmission resources shared by multiple terminal devices or group transmission resources shared by a group of terminal devices, the second transmission resource is used to transmit common DCI and / or common downlink data. The common DCI and / or common downlink data is used to transmit at least one of the following information: broadcast information, system information, paging information, and random access response information.

[0105] In some embodiments, the network device configures the same first transmission resource and the same second transmission resource for multiple terminal devices, that is, the first transmission resource and the second transmission resource are shared by multiple terminal devices; the network device configures the same sequence for multiple terminal devices, or the network device configures their respective corresponding sequences for multiple terminal devices, and the terminal devices detect the first indication information on the first transmission resource based on the configured sequence.

[0106] For example, the network device configures Sequence 1 for terminal device 1 and Sequence 1 for terminal device 2. Both terminal device 1 and terminal device 2 detect first indication information on the first transmission resource based on Sequence 1.

[0107] For example, the network device configures sequence 1 for terminal device 1 and sequence 2 for terminal device 2. Terminal device 1 detects first indication information on the first transmission resource based on sequence 1, and terminal device 2 detects first indication information on the first transmission resource based on sequence 2.

[0108] The network device is configured with a first transmission resource and a second transmission resource for transmitting common DCI and / or common downlink data. A first indication information is transmitted on the first transmission resource, the sequence corresponding to the first indication information being a common sequence. Common DCI and / or common downlink data are transmitted on the second transmission resource.

[0109] In some embodiments, multiple terminal devices detect whether there is first indication information on the first transmission resource based on the same common sequence.

[0110] For example, the network device configures a common sequence 1 for terminal device 1 and terminal device 2, and terminal device 1 and terminal device 2 detect first indication information on the first transmission resource based on the common sequence 1.

[0111] If the terminal device detects the first indication information, it detects common DCI and / or common downlink data on the second transmission resource based on the first indication information. The common DCI and common downlink data are used to transmit at least one of the following information: broadcast information, system information, paging information, and random access response information.

[0112] This includes broadcast information such as Master Information Block (MIB) information; system information such as System Information Block (SIB) information; paging information such as paging information; and random access response information such as Random Access Response (RAR) information.

[0113] In some embodiments, the network device is configured with common transport resources, including common first transport resources and common second transport resources, for transmitting common DCI and common downlink data.

[0114] The common first transmission resource and the common second transmission resource can also be referred to as cell-specific first transmission resource and cell-specific second transmission resource, or common first transmission resource and common second transmission resource.

[0115] Optionally, network devices can be configured with different types of group transmission resources. It should be noted that the "group" in group transmission resources here refers to a terminal group, not the group in the group transmission resources mentioned above.

[0116] In some embodiments, in a first configuration, the network device configures a group transmission resource shared by a group of terminal devices, including a first group transmission resource and a second group transmission resource. The second group transmission resource is used to transmit group common DCI or group common downlink data. Optionally, the terminal device group includes all terminal devices within the cell, and the first group transmission resource and the second group transmission resource can also be referred to as shared first transmission resource and shared second transmission resource. For example, the common DCI and common downlink data are used to transmit at least one of the following: slot format information, channel occupation time duration information, available resource block set information, search space set group switching information, pre-emption indication information, transmission power control (TPC), uplink transmission cancellation indication information, and wake-up indication information.

[0117] In some embodiments, in the second configuration, the network device configures a group transmission resource shared by a group of terminal devices, including a group second transmission resource. The network device configures different first transmission resources for the group of terminal devices. For example, the network device configures the same second transmission resource for the group of terminal devices, but configures different first transmission resources. For each terminal device, there is an association between its configured first transmission resource and second transmission resource; this configuration method can enable multiple terminal devices to reuse or share the second transmission resource.

[0118] For example, Figure 4 shows a schematic diagram of the configuration transmission resources provided in an exemplary embodiment of this application.

[0119] Part (a) in Figure 4 corresponds to the first configuration method described above, where the network device configures the same first transmission resource and the same second transmission resource for UE1 and UE2, and UE1 and UE2 share the first and second transmission resources. In some embodiments, the network device only sends the first indication information to UE1 to indicate the transmission content on the second transmission resource. UE1 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource. In some embodiments, the network device only sends the first indication information to UE2 to indicate the transmission content on the second transmission resource. UE2 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource.

[0120] Part (b) in Figure 4 corresponds to the second configuration described above, where the network device configures the same second transmission resource for UE1 and UE2, and different first transmission resources for UE1 and UE2, with UE1 and UE2 sharing the second transmission resource. In some embodiments, the network device only sends the first indication information for UE1 to indicate that UE1's transmission content is being transmitted on the second transmission resource, without sending the first indication information for UE2, or sends the first indication information for UE2 to indicate that there is no transmission on the second transmission resource. UE1 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource. UE2 determines that detection is not needed on the second transmission resource based on the first indication information detected on the first transmission resource. In some embodiments, the network device only sends the first indication information for UE2 to indicate that UE2's transmission content is being transmitted on the second transmission resource, without sending the first indication information for UE1, or sends the first indication information for UE1 to indicate that there is no transmission on the second transmission resource. UE2 determines whether detection is needed on the second transmission resource and the corresponding detection content (such as detecting DCI or downlink data) based on the first indication information detected on the first transmission resource. UE1 determines that detection is not needed on the second transmission resource based on the first indication information detected on the first transmission resource.

[0121] Part (c) of Figure 4 corresponds to the second configuration method described above. Part (c) of Figure 4 has the same configuration method as part (b) of Figure 4, that is, the network device configures the same second transmission resource for UE1 and UE2, and configures different first transmission resources for UE1 and UE2. UE1 and UE2 share the second transmission resource. In part (c) of Figure 4, the first indication information sent by the network device to either UE1 or UE2 indicates the value of the transmission parameters corresponding to the content transmitted on the second transmission resource. For example, the first indication information sent on the first transmission resource of UE1 indicates that the transmission resource of UE1's DCI occupies only half of the second transmission resource; the first indication information sent on the first transmission resource of UE2 also indicates that the transmission resource of UE2's DCI occupies only half of the second transmission resource, and UE1 and UE2 occupy different resources on the second transmission resource, thus allowing the two UEs to simultaneously reuse the second transmission resource for transmission.

[0122] In some embodiments, the network device configures a user-specific first transmission resource and a user-specific second transmission resource for each terminal device. The user-specific first transmission resource is used to transmit a first indication information specific to each terminal device, and the user-specific second transmission resource is used to transmit a user-specific DCI or user-specific downlink data for each terminal device.

[0123] In some embodiments, the proprietary first transmission resources of different terminal devices do not overlap, completely overlap, or partially overlap, and the proprietary second transmission resources of different terminal devices do not overlap, completely overlap, or partially overlap.

[0124] For example, Figure 5 illustrates a schematic diagram of the configuration of transmission resources provided in an exemplary embodiment of this application. The network device is configured with common transmission resources, group transmission resources, and dedicated transmission resources. The common transmission resources include two groups of common first transmission resources and two groups of common second transmission resources; the group transmission resources include two groups of group first transmission resources and two groups of group second transmission resources; and the dedicated transmission resources include eight groups of dedicated first transmission resources and dedicated second transmission resources. For the dedicated transmission resources, the network device can configure one or more dedicated first transmission resources and dedicated second transmission resources for each terminal device. Assuming the network device configures one group of common first transmission resources and one group of common second transmission resources, one group of group first transmission resources and one group of group second transmission resources, and two groups of dedicated first transmission resources and dedicated second transmission resources for a terminal device, the terminal device needs to perform detection in these four groups of transmission resources (e.g., detecting the presence of first indication information in the first transmission resources), and then detect DCI and / or downlink data in the corresponding second transmission resources. By dividing a set of transmission resources into different types of transmission resources, and with network devices configured with at least one of public transmission resources, group transmission resources, and dedicated transmission resources, the scope of terminal device detection is narrowed, and detection efficiency is improved.

[0125] In the above embodiments, a sequence is transmitted on the first transmission resource. The sequence carries first indication information, which can be used to indicate the transmission content in the second transmission resource, such as indicating the transmission of DCI on the second transmission resource. To support link adaptation, the first indication information can also be used to indicate the transmission parameters and resource location corresponding to the transmission content in the second transmission resource, such as indicating the transmission parameters corresponding to DCI. How to indicate the transmission content, transmission parameters, and resource location on the second transmission resource using the first indication information is a problem that needs to be solved.

[0126] Figure 6 illustrates a flowchart of an information indication method provided in some exemplary embodiments of this application. The method is illustrated illustratively, taking the execution of the method by a terminal device as an example. The method includes:

[0127] Step 610: Obtain first indication information on the first transmission resource, wherein the first information associated with the first indication information is used to indicate the transmission information on the second transmission resource.

[0128] The first and second transmission resources are transmission resources configured by the network device for the terminal device. Optionally, the transmission resources include, but are not limited to, resources in at least one of the following dimensions: time domain resources, frequency domain resources, code domain resources, and spatial domain resources.

[0129] In some embodiments, the terminal device acquiring the first indication information on the first transmission resource can also be understood as the terminal device receiving the first indication information on the first transmission resource, or as the terminal device monitoring or detecting the first indication information on the first transmission resource. Optionally, the first transmission resource is used to transmit the first indication information, which is carried based on a sequence or information bits, and the first information associated with the first indication information is used to indicate transmission information on the second transmission resource. Optionally, the second transmission resource is used for downlink transmission, and the second transmission resource is used to transmit DCI and / or downlink data.

[0130] In some embodiments, the first information is related information that the first indication information is mapped onto the first transmission resource in a comb-like manner. Optionally, the first information includes at least one of comb size and comb offset. For example, the first information includes comb size, or the first information includes comb offset, or the first information includes both comb size and comb offset. The resources for transmitting the first indication information are arranged in a comb-like pattern within the first transmission resource. The first transmission resource can be considered as a set of comb-like resources, or a set of transmission resources arranged in a comb-like pattern, or a set of equally spaced transmission resources, or the first transmission resource corresponds to a frequency-continuous resource, and the resources for transmitting the first indication information are distributed in a comb-like pattern within the first transmission resource.

[0131] In some embodiments, a comb-like distribution of transmission resources refers to the transmission resources being arranged or distributed at equal intervals on a time-domain symbol (or OFDM symbol). In some embodiments, a set of comb-like resources corresponds to a set of equally spaced subcarriers or resource elements (REs) on a time-domain symbol. In some embodiments, the first transmission resource includes multiple time-domain symbols, and on each time-domain symbol, the resources used to transmit the first indication information are arranged in a comb-like pattern, with different frequency domain offsets corresponding to the resources used to map the first indication information on different time-domain symbols.

[0132] In some embodiments, the comb tooth size is determined based on the spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource. Two adjacent transmission resources refer to two transmission resources that are adjacent in frequency domain position on an OFDM symbol. The comb tooth offset is used to indicate the offset (or frequency domain offset) corresponding to the comb tooth resource occupied when the first indication information is mapped on the first transmission resource. If the first indication information is mapped to multiple time domain symbols on the first transmission resource, the frequency domain offset corresponds to the frequency domain offset on the first time domain symbol among the multiple time domain symbols. That is, the comb tooth offset is used to indicate the offset corresponding to the comb tooth resource occupied when the first indication information is mapped on the first OFDM symbol in the first transmission resource. Optionally, the spacing includes a subcarrier spacing or a resource element spacing. The comb tooth size is determined based on the subcarrier spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource, or the comb tooth size is determined based on the resource element spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource. In some embodiments, a resource unit can be understood as a frequency domain unit, and the resource unit interval can be understood as a frequency domain unit interval. For example, a resource unit is a sub-band, and the resource unit interval is a sub-band interval. Typically, the first indication information is mapped to the frequency domain resource in a comb-like manner. However, if the first indication information is mapped to the time domain resource in a comb-like manner, the resource unit can be understood as a time domain unit, and the resource unit interval can be understood as a time domain unit interval. This application does not limit this.

[0133] It should be noted that the "comb tooth size" appearing in the embodiments of this application can all be understood as the interval between two adjacent transmission resources used to map the first indication information on a time domain symbol (or the same time domain symbol) in the first transmission resource; when the first transmission resource includes multiple time domain symbols, the "comb tooth offset" can all be understood as the offset of the comb tooth resource occupied when the first indication information is mapped on the first time domain symbol in the first transmission resource, which will not be elaborated further below.

[0134] For example, referring to Figure 7, the first transmission resource includes one OFDM symbol with 36 corresponding resource units in the frequency domain. The subcarrier spacing or resource unit spacing between two adjacent transmission resources used for mapping the first indication information is 4, that is, the comb tooth size is 4. When the comb tooth size is 4, the first transmission resource can include 4 comb tooth resources (each comb tooth resource can be called the first transmission sub-resource), and the 4 comb tooth resources are shown in Figures (a) to (d) of Figure 7. As shown in Figure (a) of Figure 7, one of every 4 subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the first subcarrier or the first resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 0. As shown in Figure (b) of Figure 7, one of every 4 subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the second subcarrier or the second resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 1. As shown in Figure 7(c), one of every four subcarriers or resource units is used for resource mapping. The first indication information is mapped to the third subcarrier or the third resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb offset of 2. As shown in Figure 7(d), one of every four subcarriers or resource units is used for resource mapping. The first indication information is mapped to the fourth subcarrier or the fourth resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb offset of 3.

[0135] For example, referring to Figure 8, in Figures (a) and (b), the first transmission resource includes one OFDM symbol, with 36 resource units in the frequency domain. The subcarrier spacing or resource unit spacing between two adjacent transmission resources used to map the first indication information is 2, that is, the comb tooth size is 2. As shown in Figure 8(a), one of every two subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the first subcarrier or the first resource unit of the first transmission resource, with a comb tooth offset of 0. As shown in Figure 8(b), one of every two subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the second subcarrier or the second resource unit of the first transmission resource, with a comb tooth offset of 1. In Figure 8(c), the first transmission resource includes two OFDM symbols, with 36 resource units in the frequency domain. All the transmission resources with diagonal lines in the figure constitute one comb tooth resource, and all the white transmission resources constitute another comb tooth resource. The comb resources corresponding to the first indication information include resources on the first OFDM symbol and resources on the second OFDM symbol. On each OFDM symbol, the subcarrier spacing or resource element spacing between two adjacent transmission resources used to map the first indication information is 2, that is, the comb size is 2. On the first OFDM symbol, the first indication information is mapped starting from the first subcarrier or the first resource element; on the second OFDM symbol, the first indication information is mapped starting from the second subcarrier or the second resource element. The comb offset corresponding to the comb resources used to map the first indication information is determined based on the frequency domain offset on the first OFDM symbol, that is, the comb offset is 0.

[0136] For example, referring to Figure 9, the first transmission resource includes one OFDM symbol with 36 corresponding resource elements in the frequency domain. The subcarrier spacing or resource element spacing between two adjacent transmission resources used to map the first indication information is 1, that is, the comb tooth size is 1. As shown in Figure 9, each subcarrier or resource element is used for resource mapping, and the first indication information is mapped to each subcarrier or each resource element of the comb tooth resource, with a comb tooth offset of 0.

[0137] In some embodiments, the first information associated with the first indication information is used to indicate transmission information on the second transmission resource. Optionally, the transmission information on the second transmission resource includes at least one of the following:

[0138] • The content transmitted in the second transmission resource;

[0139] • Transmission parameters corresponding to the transmission content in the second transmission resource;

[0140] • The location of transmission resources within the second transmission resource; transmission resources are the resources occupied by the transmission content within the second transmission resource.

[0141] In some embodiments, the first information includes the comb tooth size, which is used to indicate transmission information on the second transmission resource. For example, the comb tooth size is used to indicate at least one of the transmission content in the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0142] In some embodiments, the first information includes a comb tooth offset, which is used to indicate transmission information on the second transmission resource. For example, the comb tooth offset is used to indicate at least one of the transmission content in the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0143] In some embodiments, the first information includes comb tooth size and comb tooth offset, and the combination of comb tooth size and comb tooth offset is used to indicate transmission information on the second transmission resource. For example, the combination of comb tooth size and comb tooth offset is used to indicate at least one of transmission content in the second transmission resource, transmission parameters corresponding to the transmission content in the second transmission resource, and resource location of the transmission resource in the second transmission resource.

[0144] In some embodiments, the first indication information and the first information associated with the first indication information jointly indicate the transmission information on the second transmission resource, or, in other words, the first indication information and the first information associated with the first indication information jointly indicate the transmission information on the second transmission resource. Optionally, the first information associated with the first indication information indicates a first portion of the transmission information, and the first indication information is used to indicate a second portion of the transmission information. For example, the first information indicates the transmission parameters corresponding to the transmission content in the second transmission resource, and the first indication information indicates the transmission content in the second transmission resource. The first information indicates the resource location of the transmission resource in the second transmission resource, and the first indication information indicates the transmission content in the second transmission resource and / or the transmission parameters corresponding to the transmission content in the second transmission resource. This application does not limit this.

[0145] In some embodiments, before obtaining the first indication information on the first transmission resource, the terminal device also receives configuration information sent by the network device. This can also be understood as the terminal device obtaining configuration information sent by the network device. Optionally, the configuration information is used to configure an association relationship between the first transmission resource and the second transmission resource. This association relationship can also be called a correspondence relationship.

[0146] Optionally, the first transmission resource and the second transmission resource are associated, including at least one of the following: the first transmission resource and the second transmission resource have a one-to-one relationship; the first transmission resource and the second transmission resource have a one-to-many relationship; the first transmission resource and the second transmission resource have a many-to-one relationship; the first transmission resource and the second transmission resource have a many-to-many relationship.

[0147] In some embodiments, the first transmission resource and the second transmission resource are associated. Optionally, the association between the second transmission resource and the first transmission resource is reflected in at least one of the following: the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the locations of the second transmission resource and the first transmission resource based on a communication protocol; or, there is a pre-configured relationship between the locations of the second transmission resource and the first transmission resource based on a network.

[0148] In summary, the method provided in this application involves a terminal device acquiring first indication information from a first transmission resource configured on a network device. The first indication information is associated with first information used to indicate transmission information on a second transmission resource. This first information is related information mapped from the first indication information to the first transmission resource using a comb-like mapping method. For example, the first information might be the comb tooth size; comb tooth size 1 can indicate one type of transmission information, while comb tooth size 2 can indicate another. This method of dynamically indicating transmission information on the second transmission resource through different comb tooth mappings improves the flexibility of the communication system, thereby increasing resource utilization and transmission efficiency.

[0149] Figure 10 illustrates a flowchart of an information indication method provided in some exemplary embodiments of this application. The method is illustrated illustratively by example, with the method being executed by a network device. The method includes:

[0150] Step 1010: Send first indication information on the first transmission resource, wherein the first information associated with the first indication information is used to indicate the transmission information on the second transmission resource.

[0151] The first and second transmission resources are transmission resources configured by the network device for the terminal device. Optionally, the transmission resources include, but are not limited to, resources in at least one of the following dimensions: time domain resources, frequency domain resources, code domain resources, and spatial domain resources.

[0152] In some embodiments, the network device sends first indication information on the first transmission resource. This can also be understood as the network device transmitting the first indication information on the first transmission resource, or as the network device sending the first indication information through the first transmission resource. Optionally, the first transmission resource is used to transmit the first indication information, which is carried based on a sequence or information bits. The first information associated with the first indication information is used to indicate transmission information on the second transmission resource. Optionally, the second transmission resource is used for downlink transmission, and the second transmission resource is used to transmit DCI and / or downlink data.

[0153] In some embodiments, the first information is related information that the first indication information is mapped onto the first transmission resource in a comb-like manner. Optionally, the first information includes at least one of comb size and comb offset. For example, the first information includes comb size, or the first information includes comb offset, or the first information includes both comb size and comb offset. The resources for transmitting the first indication information are arranged in a comb-like pattern within the first transmission resource. The first transmission resource can be considered as a set of comb-like resources, or a set of transmission resources arranged in a comb-like pattern, or a set of equally spaced transmission resources, or the first transmission resource corresponds to a frequency-continuous resource, and the resources for transmitting the first indication information are distributed in a comb-like pattern within the first transmission resource.

[0154] In some embodiments, a set of comb-shaped resources corresponds to a set of equally spaced subcarriers or resource elements on a time-domain symbol. In some embodiments, the first transmission resource includes multiple time-domain symbols, and on each time-domain symbol, the resources for transmitting the first indication information are arranged in a comb-like pattern, with different frequency-domain offsets corresponding to the resources for mapping the first indication information on different time-domain symbols.

[0155] In some embodiments, the comb tooth size is determined based on the spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource. The comb tooth offset indicates the frequency domain offset corresponding to the comb tooth resource occupied when the first indication information is mapped on the first OFDM symbol in the first transmission resource. Optionally, the offset is based on the offset of the first subcarrier used for mapping the first indication information on the first OFDM symbol in the first transmission resource relative to the first subcarrier of the PRB containing that subcarrier. Optionally, the spacing includes a subcarrier spacing or a resource element spacing. Optionally, the offset is represented as the number of subcarriers or the number of resource elements (REs). The comb tooth size is determined based on the subcarrier spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource, or the comb tooth size is determined based on the resource element spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource. In some embodiments, a resource element can be understood as a frequency domain element, and the resource element spacing can be understood as a frequency domain element spacing; for example, a resource element is a subband, and the resource element spacing is a subband spacing. Normally, the first indication information is mapped to the frequency domain resources in a comb-like manner. However, if the first indication information is mapped to the time domain resources in a comb-like manner, the resource unit can be understood as a time domain unit, and the resource unit interval can be understood as the time domain unit interval. This application does not limit this.

[0156] For example, referring to Figure 7, the first transmission resource includes one OFDM symbol with 36 corresponding resource units in the frequency domain. The subcarrier spacing or resource unit spacing between two adjacent transmission resources used for mapping the first indication information is 4, that is, the comb tooth size is 4. As shown in Figure 7(a), one of every four subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the first subcarrier or the first resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 0. As shown in Figure 7(b), one of every four subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the second subcarrier or the second resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 1. As shown in Figure 7(c), one of every four subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the third subcarrier or the third resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 2. As shown in Figure 7(d), one of every four subcarriers or resource units is used for resource mapping. The first indication information is mapped to the fourth subcarrier or the fourth resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb offset of 3.

[0157] For example, referring to Figure 8, in Figures (a) and (b), the first transmission resource includes one OFDM symbol, with 36 resource units in the frequency domain. The subcarrier spacing or resource unit spacing between two adjacent transmission resources used to map the first indication information is 2, that is, the comb tooth size is 2. As shown in Figure 8(a), one of every two subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the first subcarrier or the first resource unit of the first transmission resource, with a comb tooth offset of 0. As shown in Figure 8(b), one of every two subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the second subcarrier or the second resource unit of the first transmission resource, with a comb tooth offset of 1. In Figure 8(c), the first transmission resource includes two OFDM symbols, with 36 resource units in the frequency domain. All the transmission resources with diagonal lines in the figure constitute one comb tooth resource, and all the white transmission resources constitute another comb tooth resource. The comb resources corresponding to the first indication information include resources on the first OFDM symbol and resources on the second OFDM symbol. On each OFDM symbol, the subcarrier spacing or resource element spacing between two adjacent transmission resources used to map the first indication information is 2, that is, the comb size is 2. On the first OFDM symbol, the first indication information is mapped starting from the first subcarrier or the first resource element; on the second OFDM symbol, the first indication information is mapped starting from the second subcarrier or the second resource element. The comb offset corresponding to the comb resources used to map the first indication information is determined based on the frequency domain offset on the first OFDM symbol, that is, the comb offset is 0.

[0158] For example, referring to Figure 9, the first transmission resource includes one OFDM symbol with 36 corresponding resource elements in the frequency domain. The subcarrier spacing or resource element spacing between two adjacent transmission resources used to map the first indication information is 1, that is, the comb tooth size is 1. As shown in Figure 9, each subcarrier or resource element is used for resource mapping, and the first indication information is mapped to each subcarrier or each resource element of the comb tooth resource, with a comb tooth offset of 0.

[0159] In some embodiments, the first information associated with the first indication information is used to indicate transmission information on the second transmission resource. Optionally, the transmission information on the second transmission resource includes at least one of the following:

[0160] • The content transmitted in the second transmission resource;

[0161] • Transmission parameters corresponding to the transmission content in the second transmission resource;

[0162] • The location of transmission resources within the second transmission resource; transmission resources are the resources occupied by the transmission content within the second transmission resource.

[0163] In some embodiments, the first information includes the comb tooth size, which is used to indicate transmission information on the second transmission resource. For example, the comb tooth size is used to indicate at least one of the transmission content in the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0164] In some embodiments, the first information includes a comb tooth offset, which is used to indicate transmission information on the second transmission resource. For example, the comb tooth offset is used to indicate at least one of the transmission content in the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0165] In some embodiments, the first information includes comb tooth size and comb tooth offset, and the combination of comb tooth size and comb tooth offset is used to indicate transmission information on the second transmission resource. For example, the combination of comb tooth size and comb tooth offset is used to indicate at least one of transmission content in the second transmission resource, transmission parameters corresponding to the transmission content in the second transmission resource, and resource location of the transmission resource in the second transmission resource.

[0166] In some embodiments, the first indication information and the first information associated with the first indication information jointly indicate the transmission information on the second transmission resource, or, in other words, the first indication information and the first information associated with the first indication information jointly indicate the transmission information on the second transmission resource. Optionally, the first information associated with the first indication information indicates a first portion of the transmission information, and the first indication information is used to indicate a second portion of the transmission information. For example, the first information indicates the transmission parameters corresponding to the transmission content in the second transmission resource, and the first indication information indicates the transmission content in the second transmission resource. The first information indicates the resource location of the transmission resource in the second transmission resource, and the first indication information indicates the transmission content in the second transmission resource and / or the transmission parameters corresponding to the transmission content in the second transmission resource. This application does not limit this.

[0167] In some embodiments, before sending the first indication information on the first transmission resource, the network device sends configuration information to the terminal device. Optionally, the configuration information is used to configure an association relationship between the first transmission resource and the second transmission resource. This association relationship can also be referred to as a correspondence relationship.

[0168] Optionally, the first transmission resource and the second transmission resource are associated, including at least one of the following: the first transmission resource and the second transmission resource have a one-to-one relationship; the first transmission resource and the second transmission resource have a one-to-many relationship; the first transmission resource and the second transmission resource have a many-to-one relationship; the first transmission resource and the second transmission resource have a many-to-many relationship.

[0169] In some embodiments, the first transmission resource and the second transmission resource are associated. Optionally, the association between the second transmission resource and the first transmission resource is reflected in at least one of the following: the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the locations of the second transmission resource and the first transmission resource based on a communication protocol; or, there is a pre-configured relationship between the locations of the second transmission resource and the first transmission resource based on a network.

[0170] In summary, the method provided in this application involves a network device sending first indication information on a configured first transmission resource. The first indication information is associated with first information used to indicate transmission information on a second transmission resource. This first information is related information mapped from the first indication information to the first transmission resource using a comb-like mapping method. For example, the first information is the comb tooth size; comb tooth size 1 can indicate one type of transmission information, and comb tooth size 2 can indicate another type. This method of dynamically indicating transmission information on the second transmission resource through different comb tooth mappings improves the flexibility of the communication system, thereby increasing resource utilization and transmission efficiency.

[0171] Next, based on the embodiments shown in Figures 6 and 10, we will further introduce the first information associated with the first indication information.

[0172] In some embodiments, a first transmission resource is used to transmit first indication information, a terminal device obtains the first indication information on the first transmission resource, and first information associated with the first indication information is used to indicate transmission information on a second transmission resource.

[0173] The first indication information is carried by a sequence or information bits.

[0174] In some embodiments, the first indication information is based on a sequence bearer, which can also be understood as the first indication information indicating in a sequence manner. The first indication information is mapped to the first transmission resource in a comb-like manner, that is, the sequence is mapped to the first transmission resource in a comb-like manner, or the sequence is mapped to a comb-like resource on the first transmission resource.

[0175] Optionally, the sequence type includes at least one of the following: Constant Amplitude Zero Auto-Corelation (CAZAC) sequence; ZC sequence; Pseudo-random sequence; Gold sequence; m-sequence; Hadamard sequence. Alternatively, the sequence used to carry the first indication information is generated or determined based on the above sequence types.

[0176] In some embodiments, the length of the sequence is determined by at least one of the following methods: based on protocol predefined information; based on configuration information sent by the network device; or based on the size of the frequency domain resources included in the first transmission resource.

For example, the sequence length L is the largest prime number less than or equal to K, K = 60, L = 59; or K = 72, L = 71; or K = 120, L = 113.

[0178] In some embodiments, the first indication information is carried based on information bits. These information bits can also be referred to as bit sequences. For example, the first indication information is carried by a bit sequence comprising L bits, where L is an integer greater than or equal to 1.

[0179] In some embodiments, information bits (or bit sequences) are processed through channel coding, modulation, etc., to generate data packets or transport blocks. Specifically, information bits may be encoded after adding a Cyclic Redundancy Check (CRC) code.

[0180] In some embodiments, the first indication information is mapped to the first transmission resource in a comb-like manner. That is, the symbols of the information bits after encoding and modulation are mapped to the first transmission resource in a comb-like manner, or the symbols of the information bits after encoding and modulation are mapped to the comb-like resources on the first transmission resource.

[0181] In some embodiments, the encoding method corresponding to the information bits includes at least one of the following: convolutional code; Manchester code; Pulse Interval Encoding (PIE); Bi-Phase Space Coding; Miller encoding; Turbo encoding; Polar code; Low Density Parity Check (LDPC); and small block length encoding. Optionally, the encoded information bits are transmitted after modulation.

[0182] In some embodiments, the modulation scheme corresponding to the information bits includes at least one of the following: On-Off Keying (OOK) modulation; Phase Shift Keying (PSK) modulation; Binary Phase Shift Keying (BPSK) modulation; Frequency Shift Keying (FSK) modulation; Quadrature Phase Shift Keying (QPSK) modulation; Quadrature Amplitude Modulation (QAM) modulation; and Orthogonal Frequency Division Multiplexing (OFDM) modulation.

[0183] The first information indicates the transmission information on the second transmission resource.

[0184] In some embodiments, the first information associated with the first indication information is used to indicate transmission information on the second transmission resource, the transmission information on the second transmission resource including at least one of the following:

[0185] Transmission Information 1: The content transmitted in the second transmission resource;

[0186] Transmission Information Two: Transmission parameters corresponding to the transmission content in the second transmission resource;

[0187] Transmission Information 3: The location of transmission resources in the second transmission resource. Transmission resources are the resources occupied by the transmission content in the second transmission resource.

[0188] In some embodiments, the transmission information on the second transmission resource is one type. Optionally, a type of transmission information on the second transmission resource is indicated by first information associated with first indication information. The type of transmission information includes any one of the following: transmission content in the second transmission resource (transmission information one), transmission parameters corresponding to the transmission content in the second transmission resource (transmission information two), and resource location of the transmission resource in the second transmission resource (transmission information three).

[0189] In some embodiments, the transmission information on the second transmission resource is at least two types. Optionally, at least two types of transmission information on the second transmission resource are indicated by first information associated with the first indication information. The at least two types of transmission information include transmission content in the second transmission resource (transmission information one), transmission parameters corresponding to the transmission content in the second transmission resource (transmission information two), and the resource location of the transmission resource in the second transmission resource (transmission information three).

[0190] For example, at least two types of transmission information include transmission content in the second transmission resource and transmission parameters corresponding to the transmission content in the second transmission resource (transmission information one and transmission information two); or, transmission content in the second transmission resource and resource location of the transmission resource in the second transmission resource (transmission information one and transmission information three); or, transmission parameters corresponding to the transmission content in the second transmission resource and resource location of the transmission resource in the second transmission resource (transmission information two and transmission information three).

[0200] 1. Regarding the transmission of information

[0201] In some embodiments, first information associated with first indication information indicates a type of transmission information on a second transmission resource, wherein the transmission information is transmission content in the second transmission resource. The transmission content in the second transmission resource is determined based on the first information associated with the first indication information. Optionally, the first information includes a comb tooth size, and the transmission content in the second transmission resource is determined based on the comb tooth size; or, the first information includes a comb tooth offset, and the transmission content in the second transmission resource is determined based on the comb tooth offset; or, the first information includes a combination of comb tooth size and comb tooth offset, and the transmission content in the second transmission resource is determined based on the combination of comb tooth size and comb tooth offset.

[0202] In some embodiments, the transmission content in the second transmission resource includes at least one of the following:

[0203] • No transmissions on the second transmission resource;

[0204] • Transmit DCI on the second transmission resource;

[0205] • Secondary transmission resources are used for uplink and downlink data transmission;

[0206] • The second transmission resource transmits DCI and downlink data.

[0207] In some embodiments, the transmission content in the second transmission resource includes no transmission on the second transmission resource. Optionally, there is no DCI transmission on the second transmission resource, or no downlink data transmission on the second transmission resource, or no DCI and downlink data transmission on the second transmission resource. First indication information is transmitted on the first transmission resource, and the terminal device determines whether there is transmission on the second transmission resource based on first information associated with the first indication information. In some embodiments, first indication information is transmitted on the first transmission resource, and the terminal device determines that there is no transmission on the second transmission resource based on the first information associated with the first indication information.

[0208] In some embodiments, if there is no transmission on the second transmission resource, the network device does not send the first indication information on the first transmission resource. That is, if the terminal device does not detect the first indication information on the first transmission resource, it indicates that there is no transmission on the second transmission resource.

[0209] In some embodiments, the transmission content in the second transmission resource includes DCI transmitted on the second transmission resource. First indication information is transmitted on the first transmission resource, and the terminal device determines that DCI will be transmitted on the second transmission resource based on first information associated with the first indication information. Optionally, the DCI is carried via PDCCH.

[0210] In some embodiments, the transmission content in the second transmission resource includes uplink and downlink data transmitted on the second transmission resource. First indication information is transmitted on the first transmission resource, and the terminal device determines the uplink and downlink data to be transmitted on the second transmission resource based on first information associated with the first indication information. Optionally, the downlink data is carried via a PDSCH.

[0211] In some embodiments, the transmission content in the second transmission resource includes uptransmitting DCI and downlink data on the second transmission resource. First indication information is transmitted on the first transmission resource, and the terminal device determines that DCI and downlink data are to be transmitted on the second transmission resource based on first information associated with the first indication information. Optionally, the DCI and downlink data are carried via a PDSCH.

[0212] 1.1 Determining the transmission content in the second transmission resource based on the comb tooth size

[0213] In some embodiments, the first information associated with the first indication information includes the comb tooth size, and the transmission information on the second transmission resource includes the transmission content in the second transmission resource. Optionally, the transmission content in the second transmission resource is determined based on the comb tooth size.

[0214] In some embodiments, different comb tooth sizes indicate the transmission content in the second transmission resource. Optionally, there is an association or correspondence between the comb tooth size and the transmission content in the second transmission resource, which is determined based on protocol predefined information or network configuration information.

[0215] In some embodiments, the first transmission resource is used to transmit first indication information, and the comb tooth size associated with the first indication information is used to determine (or be understood as indicating) the transmission content in the second transmission resource. Optionally, the network device is configured with different comb tooth sizes, and different comb tooth sizes correspond to different transmission contents in the second transmission resource.

[0216] In some embodiments, different comb tooth sizes correspond to different transmission content. The transmission content in the second transmission resource includes at least one of the following: no transmission on the second transmission resource; transmission of DCI on the second transmission resource; transmission of downlink data on the second transmission resource; and transmission of both DCI and downlink data on the second transmission resource. The correspondence between the network device configuration comb tooth size and the transmission content is shown in Table 3.

[0217] Table 3

[0218] For example, the first information includes the comb tooth size, which is determined based on the resource element spacing between two adjacent transmission resources on an OFDM symbol in the first transmission resource used to map the first indication information. Taking four possible values ​​for the comb tooth size as an example, there is a correspondence between the values ​​of the comb tooth size and the transmission content in the second transmission resource. Optionally, when the comb tooth size is the first comb tooth size, the corresponding transmission content is no transmission on the second transmission resource; when the comb tooth size is the second comb tooth size, the corresponding transmission content is DCI transmission on the second transmission resource; when the comb tooth size is the third comb tooth size, the corresponding transmission content is downlink data transmission on the second transmission resource; and when the comb tooth size is the fourth comb tooth size, the corresponding transmission content is both DCI and downlink data transmission on the second transmission resource.

[0219] For example, when the first comb tooth size is 1, that is, when the interval between two adjacent transmission resources used to map the first indication information on an OFDM symbol in the first transmission resource is 1, it is used to indicate that there is no transmission on the second transmission resource. As another example, when the second comb tooth size is 2, that is, when the interval between two adjacent transmission resources used to map the first indication information on an OFDM symbol in the first transmission resource is 2, it is used to indicate that DCI is transmitted on the second transmission resource. As another example, when the third comb tooth size is 4, that is, when the interval between two adjacent transmission resources used to map the first indication information on an OFDM symbol in the first transmission resource is 4, it is used to indicate that downlink data is transmitted on the second transmission resource. As another example, when the fourth comb tooth size is 6, that is, when the interval between two adjacent transmission resources used to map the first indication information on an OFDM symbol in the first transmission resource is 6, it is used to indicate that both DCI and downlink data are transmitted on the second transmission resource.

[0220] It should be noted that Table 3 above is merely an illustrative example of the correspondence between comb tooth size and transmitted content, and does not constitute a limitation on the correspondence between comb tooth size and transmitted content. For example, when the comb tooth size is the first comb tooth size, the transmitted content can be DCI transmitted on the second transmission resource; as another example, when the comb tooth size is the second comb tooth size, the transmitted content can be DCI and downlink data transmitted on the second transmission resource.

[0221] It should be noted that the network configuration mapping only includes a portion of the content in the table above, such as any two rows. In some implementations, the network configuration mapping includes K comb tooth sizes, and the corresponding transmission content is also K, where K is an integer greater than or equal to 1. This application does not impose any limitations on this.

[0222] 1.2 Determining the transmission content in the second transmission resource based on comb tooth offset

[0223] In some embodiments, the first information associated with the first indication information includes a comb tooth offset, and the transmission information on the second transmission resource includes the transmission content in the second transmission resource. Optionally, the transmission content in the second transmission resource is determined based on the comb tooth offset.

[0224] In some embodiments, different comb tooth offsets indicate the transmission content in the second transmission resource. Optionally, there is an association or correspondence between the comb tooth offset and the transmission content in the second transmission resource, which is determined based on protocol predefined information or network configuration information.

[0225] In some embodiments, the first transmission resource is used to transmit first indication information, and the comb offset associated with the first indication information is used to determine (or be understood as indicating) the transmission content in the second transmission resource. Optionally, the network device is configured with different comb offsets, and different comb offsets correspond to different transmission contents in the second transmission resource.

[0226] In some embodiments, different comb offsets correspond to different transmission contents. The transmission contents in the second transmission resource include at least one of the following: no transmission on the second transmission resource; transmission of DCI on the second transmission resource; transmission of downlink data on the second transmission resource; and transmission of both DCI and downlink data on the second transmission resource. The correspondence between the network device configuration comb offsets and transmission contents is shown in Table 4.

[0227] Table 4

[0228] For example, the first information includes a comb tooth offset, which indicates the offset of the comb tooth resource occupied when the first indication information is mapped on the first OFDM symbol in the first transmission resource. Taking four possible values ​​for the comb tooth offset as an example, there is a correspondence between the values ​​of the comb tooth offset and the transmission content in the second transmission resource. Optionally, when the comb tooth offset is the first comb tooth offset, the corresponding transmission content is no transmission on the second transmission resource; when the comb tooth offset is the second comb tooth offset, the corresponding transmission content is DCI transmission on the second transmission resource; when the comb tooth offset is the third comb tooth offset, the corresponding transmission content is downlink data transmission on the second transmission resource; and when the comb tooth offset is the fourth comb tooth offset, the corresponding transmission content is both DCI and downlink data transmission on the second transmission resource.

[0229] The following explanation uses the example of mapping the first indication information onto the first transmission resource with a comb tooth size of 4, specifically, taking an interval of 4 between two adjacent transmission resources used to map the first indication information on an OFDM symbol within the first transmission resource. For instance, when the first comb tooth offset is 0, meaning the offset corresponding to the comb tooth resource occupied by the first indication information when mapped onto the first OFDM symbol in the first transmission resource is 0, it indicates no transmission on the second transmission resource. Similarly, when the second comb tooth offset is 1, meaning the offset corresponding to the comb tooth resource occupied by the first indication information when mapped onto the first OFDM symbol in the first transmission resource is 1, it indicates DCI transmission on the second transmission resource. And again, when the third comb tooth offset is 2, meaning the offset corresponding to the comb tooth resource occupied by the first indication information when mapped onto the first OFDM symbol in the first transmission resource is 2, it indicates downlink data transmission on the second transmission resource. For example, when the fourth comb tooth offset is 3, that is, when the offset of the comb tooth resource occupied by the first indication information when it is mapped on the first OFDM symbol in the first transmission resource is 3, it is used to indicate the transmission of DCI and downlink data on the second transmission resource.

[0230] It should be noted that Table 4 above is merely an illustrative example of the correspondence between comb tooth offsets and transmitted content, and does not constitute a limitation on the correspondence between comb tooth offsets and transmitted content. For example, when the comb tooth offset is the first comb tooth offset, the transmitted content can indicate uplink / downlink data transmission on the second transmission resource; as another example, when the comb tooth offset is the second comb tooth offset, the transmitted content can indicate no transmission on the second transmission resource.

[0231] It should be noted that the network configuration mapping only includes a portion of the content in the table above, such as any two rows. In some implementations, the network configuration mapping includes K comb offsets, and the corresponding transmission content is also K, where K is an integer greater than or equal to 1. This application does not impose any limitations on this.

[0232] 1.3 Determine the transmission content in the second transmission resource based on the combination of comb tooth size and comb tooth offset.

[0233] In some embodiments, the first information associated with the first indication information includes the comb tooth size and comb tooth offset, and the transmission information on the second transmission resource includes the transmission content in the second transmission resource. Optionally, the transmission content in the second transmission resource is determined based on a combination of the comb tooth size and the comb tooth offset.

[0234] In some embodiments, different combinations of comb tooth sizes and comb tooth offsets indicate the transmission content in the second transmission resource. Optionally, there is an association or correspondence between the combination of comb tooth sizes and comb tooth offsets and the transmission content in the second transmission resource, and this association or correspondence is determined based on protocol predefined information or network configuration information.

[0235] In some embodiments, the first transmission resource is used to transmit first indication information, and the comb tooth size and comb tooth offset associated with the first indication information are used to determine (or be understood as indicating) the transmission content in the second transmission resource. Optionally, the network device is configured with different comb tooth sizes and comb tooth offsets, and different comb tooth sizes and comb tooth offsets correspond to different transmission content in the second transmission resource.

[0236] In some embodiments, different comb tooth sizes and comb tooth offsets correspond to different transmission content. The transmission content in the second transmission resource includes at least one of the following: no transmission on the second transmission resource; transmission of DCI on the second transmission resource; transmission of downlink data on the second transmission resource; transmission of both DCI and downlink data on the second transmission resource. The correspondence between the network device configuration of comb tooth size and comb tooth offset and the transmission content is shown in Table 5.

[0237] Table 5

[0238] For example, the first information includes a combination of comb tooth size and comb tooth offset. Taking four combinations of comb tooth size and comb tooth offset as an example, each combination of comb tooth size and comb tooth offset corresponds to the transmission content in the second transmission resource. Optionally, when the combination of comb tooth size and comb tooth offset is the first combination, the corresponding transmission content is no transmission on the second transmission resource; when the combination of comb tooth size and comb tooth offset is the second combination, the corresponding transmission content is DCI transmission on the second transmission resource; when the combination of comb tooth size and comb tooth offset is the third combination, the corresponding transmission content is downlink data transmission on the second transmission resource; and when the combination of comb tooth size and comb tooth offset is the fourth combination, the corresponding transmission content is both DCI and downlink data transmission on the second transmission resource.

[0239] For example, when the first combination is a comb tooth size of 4 and a comb tooth offset of 0, it indicates that there is no transmission on the second transmission resource. As another example, when the second combination is a comb tooth size of 4 and a comb tooth offset of 2, it indicates that DCI is being transmitted on the second transmission resource. As another example, when the third combination is a comb tooth size of 2 and a comb tooth offset of 0, it indicates that downlink data is being transmitted on the second transmission resource. As another example, when the fourth combination is a comb tooth size of 2 and a comb tooth offset of 1, it indicates that both DCI and downlink data are being transmitted on the second transmission resource.

[0240] It should be noted that Table 5 above is merely an illustrative example of the correspondence between comb tooth size and comb tooth offset and the transmitted content, and does not constitute a limitation on the correspondence between comb tooth size and comb tooth offset and the transmitted content. For example, when the comb tooth size and comb tooth offset are in the first combination, the transmitted content can indicate DCI and downlink data transmitted on the second transmission resource.

[0241] It should be noted that the network configuration correspondence only includes a portion of the content in the table above, such as any two rows. In some implementations, the network configuration correspondence includes K combinations of comb tooth size and comb tooth offset, and the corresponding transmission content is also K, where K is an integer greater than or equal to 1. This application does not impose any limitations on this.

The first candidate parameter corresponds to one transmission parameter or a set of transmission parameters.

[0251] In some embodiments, the value of the first candidate parameter may correspond to the value of a transmission parameter. For example, the value of the first candidate parameter may correspond to the value of the DCI format. Another example is that the value of the first candidate parameter may correspond to the aggregation level of the DCI. Yet another example is that the value of the first candidate parameter may correspond to the modulation scheme of the downlink data.

[0252] In some embodiments, the value of the first candidate parameter may correspond to a set of transmission parameter values. For example, the value of the first candidate parameter may correspond to the value of the DCI format and the value of the aggregation level. As another example, the value of the first candidate parameter may correspond to the value of the downlink data modulation scheme and the value of the layer number information.

[0259] In some embodiments, determining the values ​​of transmission parameters corresponding to downlink data based on the comb tooth size includes at least one of the following: determining the value of the modulation scheme corresponding to the downlink data based on the comb tooth size; determining the value of the MCS level corresponding to the downlink data based on the comb tooth size; determining the value of the MCS table corresponding to the downlink data based on the comb tooth size; determining the value of the TBS corresponding to the downlink data based on the comb tooth size; determining the value of the coding scheme corresponding to the downlink data based on the comb tooth size; determining the value of the antenna port information corresponding to the downlink data based on the comb tooth size; determining the value of the layer number information corresponding to the downlink data based on the comb tooth size; determining the value of the DMRS information corresponding to the downlink data based on the comb tooth size; determining the value of the parameter information for generating the DMRS sequence corresponding to the downlink data based on the comb tooth size; determining the value of the HARQ information associated with the downlink data based on the comb tooth size; and determining the value of the spatial filter associated with the downlink data based on the comb tooth size.

[0260] In some embodiments, the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined based on the comb tooth size from multiple or multiple sets of first candidate parameter values. The first candidate parameter corresponds to one transmission parameter or a set of transmission parameters.

[0261] 2.1.1 For the first candidate parameter, there is a corresponding transmission parameter.

[0262] In some embodiments, the value of the first candidate parameter may correspond to the value of a transmission parameter. Optionally, the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined from multiple first candidate parameter values ​​based on the comb tooth size.

[0263] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0264] For example, consider the aggregation level corresponding to the transmission parameter DCI. The aggregation level value is a subset of {1, 2, 4, 8, 16, 32}. Optionally, the aggregation level value corresponding to DCI is determined based on the comb tooth size. Different comb tooth sizes correspond to different aggregation level values. The relationship between the network device's configured comb tooth size and aggregation level value is shown in Table 6.

[0265] Table 6

[0266] For example, the first information includes the comb tooth size, which is determined based on the resource unit interval between two adjacent transmission resources used to map the first indication information on an OFDM symbol in the first transmission resource. Taking four possible values ​​for the comb tooth size as an example, there is a first correspondence between the values ​​of the comb tooth size and the values ​​of the aggregation levels corresponding to the DCI. Optionally, when the comb tooth size is the first comb tooth size, it corresponds to the first aggregation level; when the comb tooth size is the second comb tooth size, it corresponds to the second aggregation level; when the comb tooth size is the third comb tooth size, it corresponds to the third aggregation level; and when the comb tooth size is the fourth comb tooth size, it corresponds to the fourth aggregation level. The first, second, third, and fourth aggregation levels mentioned above each include any one of the aggregation levels {1, 2, 4, 8, 16, 32}. Optionally, the first, second, third, and fourth aggregation levels may not be completely identical or may be different from each other, and this application does not limit this.

[0267] For example, when the first comb tooth size is 1, it indicates that the polymerization level corresponding to DCI is 1. As another example, when the second comb tooth size is 2, it indicates that the polymerization level corresponding to DCI is 2. As another example, when the third comb tooth size is 4, it indicates that the polymerization level corresponding to DCI is 4. As another example, when the fourth comb tooth size is 6, it indicates that the polymerization level corresponding to DCI is 8.

[0268] It should be noted that Table 6 above is merely an exemplary illustration of the first correspondence between the comb tooth size and the aggregation level values. The method implemented in this application is not limited to the correspondence in Table 6. In some embodiments, the first correspondence of network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the first correspondence of network configuration includes K comb tooth sizes, and the corresponding aggregation level values ​​are also K, where K is an integer greater than or equal to 1.

[0269] For example, consider the modulation scheme corresponding to downlink data as the transmission parameter. The modulation scheme includes at least one of the following: QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, 4096QAM, or other modulation schemes. Optionally, the modulation scheme value corresponding to the downlink data is determined based on the comb tooth size. Different comb tooth sizes correspond to different modulation scheme values. The relationship between the network device's configured comb tooth size and the modulation scheme value is shown in Table 7.

[0270] Table 7

[0271] For example, the first information includes the comb tooth size, which is determined based on the resource element interval between two adjacent transmission resources on an OFDM symbol in the first transmission resource used to map the first indication information. Taking four possible values ​​for the comb tooth size as an example, there is a first correspondence between the values ​​of the comb tooth size and the modulation scheme corresponding to the downlink data. Optionally, when the comb tooth size is the first comb tooth size, it corresponds to the first modulation scheme; when the comb tooth size is the second comb tooth size, it corresponds to the second modulation scheme; when the comb tooth size is the third comb tooth size, it corresponds to the third modulation scheme; and when the comb tooth size is the fourth comb tooth size, it corresponds to the fourth modulation scheme. The above modulation schemes can be different, and the first, second, third, and fourth modulation schemes can be any one of QPSK, 16QAM, 64QAM, 256QAM, 1024QAM, and 4096QAM, respectively. Optionally, the first, second, third, and fourth modulation schemes may not be completely the same or may be different from each other, and this application does not limit this.

[0272] For example, when the first comb tooth size is 1, it indicates that the modulation scheme corresponding to the downlink data is QPSK modulation. As another example, when the second comb tooth size is 2, it indicates that the modulation scheme corresponding to the downlink data is 16QAM modulation. As yet another example, when the third comb tooth size is 4, it indicates that the modulation scheme corresponding to the downlink data is 64QAM modulation. And as yet another example, when the fourth comb tooth size is 6, it indicates that the modulation scheme corresponding to the downlink data is 256QAM modulation.

[0273] It should be noted that Table 7 above is merely an exemplary illustration of the first correspondence between the comb tooth size and the modulation scheme values. The method implemented in this application is not limited to the correspondence in Table 7. In some embodiments, the first correspondence of network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the first correspondence of network configuration includes K comb tooth sizes, and the corresponding modulation scheme values ​​are also K, where K is an integer greater than or equal to 1.

[0274] 2.1.2 For the first candidate parameter, a set of transmission parameters is provided.

[0275] In some embodiments, the value of the first candidate parameter may correspond to a set of transmission parameter values. Optionally, the transmission parameter value corresponding to the transmission content in the second transmission resource is determined from multiple sets of first candidate parameter values ​​based on the comb tooth size.

[0276] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0277] For example, consider transmission parameters including the aggregation level corresponding to the DCI and the modulation scheme of the downlink data. Optionally, the aggregation level corresponding to the DCI and the modulation scheme of the downlink data are determined based on the comb tooth size. Different comb tooth sizes correspond to different aggregation level values ​​and different downlink data modulation scheme values, respectively. The first correspondence between the comb tooth size configured in the network device and a set of transmission parameters (the aggregation level corresponding to the DCI and the modulation scheme corresponding to the downlink data) is shown in Table 8.

[0278] Table 8

[0279] For example, the first information includes the comb tooth size, which is determined based on the resource element spacing between two adjacent transmission resources on an OFDM symbol in the first transmission resource used to map the first indication information. Taking four possible values ​​for the comb tooth size as an example, the values ​​of the comb tooth size have a first correspondence with the aggregation level corresponding to the DCI and the modulation scheme corresponding to the downlink data. Optionally, when the comb tooth size is the first comb tooth size, it corresponds to the first aggregation level and the first modulation scheme; when the comb tooth size is the second comb tooth size, it corresponds to the second aggregation level and the second modulation scheme; when the comb tooth size is the third comb tooth size, it corresponds to the third aggregation level and the third modulation scheme; and when the comb tooth size is the fourth comb tooth size, it corresponds to the fourth aggregation level and the fourth modulation scheme.

[0280] For example, when the first comb tooth size is 1, it indicates that the aggregation level corresponding to DCI is 1, and that the modulation scheme corresponding to the downlink data is QPSK modulation. As another example, when the second comb tooth size is 2, it indicates that the aggregation level corresponding to DCI is 2, and that the modulation scheme corresponding to the downlink data is 16QAM modulation. As yet another example, when the third comb tooth size is 4, it indicates that the aggregation level corresponding to DCI is 4, and that the modulation scheme corresponding to the downlink data is 64QAM modulation. As yet another example, when the fourth comb tooth size is 6, it indicates that the aggregation level corresponding to DCI is 8, and that the modulation scheme corresponding to the downlink data is 256QAM modulation.

[0281] It should be noted that Table 8 above is merely an exemplary illustration of the first correspondence between the comb tooth size and the values ​​of the aggregation level and modulation scheme. The method implemented in this application is not limited to the correspondence in Table 8. In some embodiments, the first correspondence of network configuration only includes a portion of the contents of the table above, such as only any two rows in the table; in some embodiments, the first correspondence of network configuration includes K comb tooth sizes, and the corresponding values ​​of the modulation scheme and aggregation level are also K, where K is an integer greater than or equal to 1.

[0282] 2.2 Determining the values ​​of transmission parameters corresponding to the transmission content in the second transmission resource based on comb tooth offset

[0283] In some embodiments, the first information associated with the first indication information includes a comb tooth offset, and the transmission information on the second transmission resource includes transmission parameters corresponding to the transmission content in the second transmission resource. Optionally, the value of the transmission parameters corresponding to the transmission content in the second transmission resource is determined based on the comb tooth offset.

[0284] In some embodiments, the first information includes a comb tooth offset, which has B1 possible values, and the transmission parameters have B2 possible values. There is a first correspondence between the comb tooth offset values ​​and the transmission parameter values. Here, B1 and B2 are integers greater than or equal to 1, and the first correspondence is determined based on protocol predefined information or network configuration information.

[0285] In some embodiments, determining the transmission parameter values ​​corresponding to the DCI based on the comb tooth offset includes at least one of the following: determining the format value corresponding to the DCI based on the comb tooth offset; determining the bit number information value corresponding to the DCI based on the comb tooth offset; determining the encoding method value corresponding to the DCI based on the comb tooth offset; determining the modulation method value corresponding to the DCI based on the comb tooth offset; determining the aggregation level value corresponding to the DCI based on the comb tooth offset; determining the number of CCEs corresponding to the DCI based on the comb tooth offset; determining the number of resources used for transmitting the DCI based on the comb tooth offset; determining the spatial filter value associated with the DCI based on the comb tooth offset; determining the DMRS information value associated with the DCI based on the comb tooth offset; determining the parameter information value for generating the DMRS sequence associated with the DCI based on the comb tooth offset; and determining the first identification information value associated with the DCI based on the comb tooth offset.

[0286] In some embodiments, determining the values ​​of transmission parameters corresponding to downlink data based on comb offset includes at least one of the following: determining the value of modulation scheme corresponding to downlink data based on comb offset; determining the value of MCS level corresponding to downlink data based on comb offset; determining the value of MCS table corresponding to downlink data based on comb offset; determining the value of TBS corresponding to downlink data based on comb offset; determining the value of coding scheme corresponding to downlink data based on comb offset; determining the value of antenna port information corresponding to downlink data based on comb offset; determining the value of layer number information corresponding to downlink data based on comb offset; determining the value of DMRS information corresponding to downlink data based on comb offset; determining the value of parameter information for generating the DMRS sequence corresponding to downlink data based on comb offset; determining the value of HARQ information associated with downlink data based on comb offset; and determining the value of spatial filter associated with downlink data based on comb offset.

[0287] In some embodiments, the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined based on the comb tooth offset from multiple or multiple sets of first candidate parameter values. Each candidate parameter corresponds to one transmission parameter or a set of transmission parameters.

[0288] 2.2.1 For the first candidate parameter, there is a corresponding transmission parameter.

[0289] In some embodiments, the value of the first candidate parameter may correspond to the value of a transmission parameter. Optionally, the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined from multiple first candidate parameter values ​​based on the comb tooth offset.

[0290] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0291] For example, consider the number of CCEs corresponding to the transmission parameter DCI. The downlink control channel is composed of one or more CCEs, and the CCE is the basic unit used by the downlink control channel to transmit the DCI. Optionally, the number of CCEs corresponding to the DCI is determined based on the comb offset. Different comb offsets correspond to different CCE values. The relationship between the comb size and the number of CCEs configured in the network device is shown in Table 9.

[0292] Table 9

[0293] For example, the first information includes a comb tooth offset, which indicates the offset of the comb tooth resources occupied when the first indication information is mapped on the first OFDM symbol in the first transmission resource. Taking four possible values ​​for the comb tooth offset as an example, there is a correspondence between the values ​​of the comb tooth offset and the number of CCEs corresponding to the DCI. Optionally, when the comb tooth offset is the first comb tooth offset, it corresponds to the first number of CCEs; when the comb tooth offset is the second comb tooth offset, it corresponds to the second number of CCEs; when the comb tooth offset is the third comb tooth offset, it corresponds to the third number of CCEs; and when the comb tooth offset is the fourth comb tooth offset, it corresponds to the fourth number of CCEs.

[0294] The following example illustrates how the first indication information is mapped onto a first transmission resource with a comb tooth size of 4. Specifically, it's illustrated by an example where the interval between two adjacent transmission resources used to map the first indication information on an OFDM symbol within the first transmission resource is 4. For instance, when the first comb tooth offset is 0, the number of CCEs corresponding to the indicated DCI is 32. As another example, when the second comb tooth offset is 1, the number of CCEs corresponding to the indicated DCI is 16. As yet another example, when the third comb tooth offset is 2, the number of CCEs corresponding to the indicated DCI is 8. And as yet another example, when the fourth comb tooth offset is 3, the number of CCEs corresponding to the indicated DCI is 4.

[0295] It should be noted that Table 9 above is merely an exemplary illustration of the first correspondence between the comb tooth size and the number of CCEs, and the method implemented in this application is not limited to the correspondence in Table 9. In some embodiments, the first correspondence of network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the first correspondence of network configuration includes K comb tooth sizes, and the corresponding number of CCEs is also K, where K is an integer greater than or equal to 1.

[0296] 2.2.2 For the first candidate parameter, a set of transmission parameters is provided.

[0297] In some embodiments, the value of the first candidate parameter may correspond to a set of transmission parameter values. Optionally, the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined from multiple sets of first candidate parameter values ​​based on the comb tooth offset.

[0298] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0299] For example, consider transmission parameters including the number of CCEs corresponding to the DCI and the antenna port information corresponding to the downlink data. Optionally, the value of the number of CCEs corresponding to the DCI and the value of the antenna port information corresponding to the downlink data are determined based on the comb offset. Different comb offsets correspond to different values ​​of the number of CCEs and different values ​​of the antenna port information. The first correspondence between the comb offset configured in the network device and a set of transmission parameters (the number of CCEs corresponding to the DCI and the antenna port information corresponding to the downlink data) is shown in Table 10.

[0300] Table 10

[0301] For example, the first information includes a comb tooth offset, which indicates the offset of the comb tooth resources occupied when the first indication information is mapped on the first OFDM symbol in the first transmission resource. Taking the comb tooth offset having four values ​​as an example, the values ​​of the comb tooth offset have a first correspondence with the values ​​of the number of CCEs corresponding to the DCI and the values ​​of the antenna port information corresponding to the downlink data. Optionally, when the comb tooth offset is the first comb tooth offset, it corresponds to the first number of CCEs and the first antenna port; when the comb tooth offset is the second comb tooth offset, it corresponds to the second number of CCEs and the second antenna port; when the comb tooth offset is the third comb tooth offset, it corresponds to the third number of CCEs and the third antenna port; and when the comb tooth offset is the fourth comb tooth offset, it corresponds to the fourth number of CCEs and the fourth antenna port.

[0302] The following example illustrates how the first indication information is mapped onto a first transmission resource with a comb tooth size of 4. Specifically, it's illustrated by an interval of 4 between two adjacent transmission resources on an OFDM symbol within the first transmission resource used to map the first indication information. For instance, when the first comb tooth offset is 0, it indicates that the number of CCEs corresponding to the DCI is 4, and that downlink data supports single-antenna port transmission. As another example, when the second comb tooth offset is 1, it indicates that the number of CCEs corresponding to the DCI is 8, and that downlink data supports 2-antenna port transmission. As yet another example, when the third comb tooth offset is 2, it indicates that the number of CCEs corresponding to the DCI is 16, and that downlink data supports 4-antenna port transmission. And as yet another example, when the fourth comb tooth offset is 3, it indicates that the number of CCEs corresponding to the DCI is 32, and that downlink data supports 8-antenna port transmission.

[0303] It should be noted that Table 10 above is merely an exemplary illustration of the first correspondence between the comb tooth offset, the number of CCEs, and the antenna port information. The method implemented in this application is not limited to the correspondence in Table 10. In some embodiments, the first correspondence of network configuration only includes a portion of the content in the table above, such as only any two rows in the table; in some embodiments, the first correspondence of network configuration includes K comb tooth offsets, and the corresponding values ​​of the number of CCEs and the antenna port information are also K, where K is an integer greater than or equal to 1.

[0305] In some embodiments, the first information associated with the first indication information includes the comb tooth size and comb tooth offset, and the transmission information on the second transmission resource includes the transmission parameters corresponding to the transmission content in the second transmission resource. Optionally, the value of the transmission parameters corresponding to the transmission content in the second transmission resource is determined based on the combination of the comb tooth size and the comb tooth offset.

[0306] In some embodiments, the first information includes the comb tooth size and the comb tooth offset. The combined values ​​of the comb tooth size and the comb tooth offset include C1 values, and the values ​​of the transmission parameters include C2 values. There is a first correspondence between the combined values ​​of the comb tooth size and the comb tooth offset and the values ​​of the transmission parameters. Wherein, C1 and C2 are integers greater than or equal to 1, and the first correspondence is determined based on protocol predefined information or network configuration information.

[0307] In some embodiments, the values ​​of the transmission parameters corresponding to the DCI are determined based on a combination of comb tooth size and comb tooth offset, including at least one of the following: determining the value of the format corresponding to the DCI based on a combination of comb tooth size and comb tooth offset; determining the value of the bit number information corresponding to the DCI based on a combination of comb tooth size and comb tooth offset; determining the value of the encoding method corresponding to the DCI based on a combination of comb tooth size and comb tooth offset; determining the value of the modulation method corresponding to the DCI based on a combination of comb tooth size and comb tooth offset; and determining the value of the aggregation level corresponding to the DCI based on a combination of comb tooth size and comb tooth offset.

[0308] In some embodiments, determining the values ​​of transmission parameters corresponding to downlink data based on a combination of comb tooth size and comb tooth offset includes at least one of the following: determining the value of modulation scheme corresponding to downlink data based on a combination of comb tooth size and comb tooth offset; determining the value of MCS level corresponding to downlink data based on a combination of comb tooth size and comb tooth offset; determining the value of MCS table corresponding to downlink data based on a combination of comb tooth size and comb tooth offset; determining the value of TBS corresponding to downlink data based on a combination of comb tooth size and comb tooth offset; and determining the value of coding scheme corresponding to downlink data based on a combination of comb tooth size and comb tooth offset.

[0309] In some embodiments, based on a combination of comb tooth size and comb tooth offset, the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined from multiple or multiple sets of first candidate parameter values. Each candidate parameter corresponds to one transmission parameter or a set of transmission parameters.

[0310] 2.3.1 For the first candidate parameter, there is a corresponding transmission parameter.

[0311] In some embodiments, the value of the first candidate parameter may correspond to the value of a transmission parameter. Optionally, based on a combination of comb tooth size and comb tooth offset, the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined from among multiple first candidate parameter values.

[0312] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0313] For example, let's take the aggregation level corresponding to the transmission parameter DCI as an example. Optionally, the aggregation level corresponding to DCI is determined based on the combination of comb tooth size and comb tooth offset. Different combinations of comb tooth size and comb tooth offset correspond to different aggregation level values. The relationship between the combination of comb tooth size and comb tooth offset configured in the network device and the aggregation level value is shown in Table 11.

[0314] Table 11

[0315] For example, the first information includes a combination of comb tooth size and comb tooth offset. Taking four combinations of comb tooth size and comb tooth offset as an example, the combined values ​​of comb tooth size and comb tooth offset have a first correspondence with the values ​​of the aggregation level corresponding to DCI. Optionally, when the combination of comb tooth size and comb tooth offset is the first combination, it corresponds to the first aggregation level; when the combination of comb tooth size and comb tooth offset is the second combination, it corresponds to the second aggregation level; when the combination of comb tooth size and comb tooth offset is the third combination, it corresponds to the third aggregation level; and when the combination of comb tooth size and comb tooth offset is the fourth combination, it corresponds to the fourth aggregation level.

[0316] For example, the first combination, where the comb tooth size is 4 and the comb tooth offset is 0, indicates that the aggregation level corresponding to DCI is 1. As another example, the second combination, where the comb tooth size is 4 and the comb tooth offset is 2, indicates that the aggregation level corresponding to DCI is 2. As yet another example, the third combination, where the comb tooth size is 2 and the comb tooth offset is 0, indicates that the aggregation level corresponding to DCI is 4. As yet another example, the fourth combination, where the comb tooth size is 2 and the comb tooth offset is 1, indicates that the aggregation level corresponding to DCI is 8.

[0317] It should be noted that Table 11 above is merely an illustrative example of the first correspondence between the combined values ​​of comb tooth size and comb tooth offset and the values ​​of aggregation levels. The method implemented in this application is not limited to the correspondence in Table 11. In some embodiments, the first correspondence of network configuration only includes a portion of the contents of the table above, such as only any two rows in the table; in some embodiments, the first correspondence of network configuration includes K combinations of comb tooth size and comb tooth offset, and the corresponding aggregation level values ​​are also K, where K is an integer greater than or equal to 1.

[0318] 2.3.2 For the first candidate parameter, a set of transmission parameters is provided.

[0319] In some embodiments, the value of the first candidate parameter may correspond to a set of transmission parameter values. Optionally, based on a combination of comb tooth size and comb tooth offset, the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined from multiple sets of first candidate parameter values.

[0320] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0321] For example, consider transmission parameters including the aggregation level corresponding to the DCI and the modulation scheme of the downlink data. Optionally, the aggregation level corresponding to the DCI and the modulation scheme of the downlink data are determined based on the combination of comb tooth size and comb tooth offset. Different combinations of comb tooth size and comb tooth offset correspond to different aggregation level values ​​and different downlink data modulation scheme values, respectively. The first correspondence between the combination of comb tooth size and comb tooth offset configured in the network device and a set of transmission parameters (the aggregation level corresponding to the DCI and the modulation scheme corresponding to the downlink data) is shown in Table 12.

[0322] Table 12

[0323] For example, the first information includes a combination of comb tooth size and comb tooth offset. Taking four combinations of comb tooth size and comb tooth offset as an example, the combined values ​​of comb tooth size and comb tooth offset have a first correspondence with the aggregation level value corresponding to DCI and the modulation scheme corresponding to downlink data. Optionally, when the combination of comb tooth size and comb tooth offset is the first combination, it corresponds to the first aggregation level and the first modulation scheme; when the combination of comb tooth size and comb tooth offset is the second combination, it corresponds to the second aggregation level and the second modulation scheme; when the combination of comb tooth size and comb tooth offset is the third combination, it corresponds to the third aggregation level and the third modulation scheme; and when the combination of comb tooth size and comb tooth offset is the fourth combination, it corresponds to the fourth aggregation level and the fourth modulation scheme.

[0324] For example, when the first combination is a comb tooth size of 4 and a comb tooth offset of 0, it indicates that the aggregation level corresponding to DCI is 1, and that the modulation mode corresponding to the downlink data is QPSK modulation. As another example, when the second combination is a comb tooth size of 4 and a comb tooth offset of 2, it indicates that the aggregation level corresponding to DCI is 2, and that the modulation mode corresponding to the downlink data is 16QAM modulation. As yet another example, when the third combination is a comb tooth size of 2 and a comb tooth offset of 0, it indicates that the aggregation level corresponding to DCI is 4, and that the modulation mode corresponding to the downlink data is 64QAM modulation. As yet another example, when the fourth combination is a comb tooth size of 2 and a comb tooth offset of 1, it indicates that the aggregation level corresponding to DCI is 8, and that the modulation mode corresponding to the downlink data is 256QAM modulation.

[0325] It should be noted that Table 12 above is merely an illustrative example of the first correspondence between the combined values ​​of comb tooth size and comb tooth offset, and the values ​​of aggregation level and modulation scheme. The method implemented in this application is not limited to the correspondence in Table 12. In some embodiments, the first correspondence of network configuration only includes a portion of the contents of the table above, such as only any two rows in the table; in some embodiments, the first correspondence of network configuration includes K combinations of comb tooth size and comb tooth offset, and the corresponding values ​​of aggregation level and modulation scheme are also K, where K is an integer greater than or equal to 1.

[0329] In some embodiments, the resource location includes a location in the time domain dimension. The location in the time domain dimension includes at least one of a time domain start position, a time domain end position, and a number of time domain units. The time domain start position refers to the starting position of the transmitted content on the second transmission resource in the time domain dimension. The time domain end position refers to the ending position of the transmitted content on the second transmission resource in the time domain dimension. The number of time domain units refers to the number of time units occupied by the transmitted content on the second transmission resource in the time domain dimension. Optionally, the transmission resource of the second transmission resource is divided into multiple time units. For example, the time domain start position corresponds to the position of the first time unit, and the number of time domain units of the transmitted content on the second transmission resource corresponds to one or more consecutive time units starting from the first time unit. The unit of time unit can be any of the following: frame, subframe, time slot, mini-time slot, sub-time slot, symbol, symbol group, or unit based on other time domain units. It should be noted that the time domain unit is not limited to the units listed above; units defined in future communication protocols also apply to this application.

[0330] In some embodiments, the resource location includes a location in the frequency domain dimension. The location in the frequency domain dimension includes at least one of a frequency domain start position, a frequency domain end position, and a number of frequency domain units. The frequency domain start position refers to the starting position of the transmitted content on the second transmission resource in the frequency domain dimension. The frequency domain end position refers to the ending position of the transmitted content on the second transmission resource in the frequency domain dimension. The number of frequency domain units refers to the number of frequency domain units occupied by the transmitted content on the second transmission resource in the frequency domain dimension.

The unit of the frequency domain unit can be any of the following: bandwidth, carrier, physical resource block (PRB), bandwidth part (BWP), subband, subchannel, subcarrier, or a unit based on other frequency domain units. It should be noted that the frequency domain unit is not limited to the units listed above; units defined in future communication protocols also apply to this application.

[0331] In some embodiments, resource location includes location in a logical resource dimension. Location in a logical resource dimension includes at least one of a logical resource unit start position, a logical resource unit end position, and a number of logical resource units. The logical resource unit start position refers to the starting position of the transmitted content on the second transmission resource in the logical resource dimension. The logical resource unit end position refers to the ending position of the transmitted content on the second transmission resource in the logical resource dimension. The number of logical resource units refers to the number of logical resource units occupied by the transmitted content on the second transmission resource in the logical resource dimension. Optionally, the transmission resource of the second transmission resource corresponds to multiple logical resource units. For example, the logical resource unit start position corresponds to the position of the first logical resource unit, and the number of logical resource units of the transmitted content on the second transmission resource corresponds to one or more consecutive logical resource units starting from the first logical resource unit. The unit of a logical resource unit can be any of the following: a resource unit group (REG), a control channel unit (CCE), a virtual resource block (VRB), or a unit based on other logical resource units. It should be noted that logical resource units are not limited to the units listed above; units defined in future communication protocols also apply to this application.

[0332] In some embodiments, a mapping relationship exists between the logical resource and the physical resource corresponding to the second transmission resource. This mapping relationship indicates how the logical resource is mapped to the physical resource. Optionally, the corresponding physical resource can be determined based on the logical resource. For example, as shown in FIG11, Virtual Resource Blocks (VRBs) are mapped to Physical Resource Blocks (PRBs). For example, the VRB with index 0 is mapped to the PRB with index 0, the VRB with index 1 is mapped to the PRB with index 8, the VRB with index 2 is mapped to the PRB with index 4, the VRB with index 3 is mapped to the PRB with index 12, the VRB with index 4 is mapped to the PRB with index 2, and so on. By mapping VRBs to distributed PRBs, this method can reduce the impact of interference.

[0333] In some embodiments, the resource location of the transmission resource in the second transmission resource is determined based on the first information from multiple or multiple sets of second candidate parameter values. The second candidate parameter corresponds to one resource location or a set of resource locations.

[0334] In some embodiments, the value of the second candidate parameter may correspond to the value of a transmission parameter. For example, the value of the second candidate parameter may correspond to the value of the start position of the transmission resource in the time domain within the second transmission resource. Another example is that the value of the second candidate parameter may correspond to the value of the transmission resource in the start position of the transmission resource in the frequency domain within the second transmission resource. Yet another example is that the value of the second candidate parameter may correspond to the value of the transmission resource in the end position of the transmission resource in the frequency domain within the second transmission resource.

[0340] Optionally, the first indication information is used to indicate the transmission content and the corresponding transmission parameters on the second transmission resource, and the first information associated with the first indication information indicates the resource location corresponding to the transmission content in the second transmission resource.

[0341] 3.1 Determining the resource location of transmission resources in the second transmission resource based on comb tooth size

[0342] In some embodiments, the first information associated with the first indication information includes the comb tooth size, and the transmission information on the second transmission resource includes the resource location of the transmission resource within the second transmission resource. Optionally, the resource location of the transmission resource within the second transmission resource is determined based on the comb tooth size.

[0343] In some embodiments, the first information includes the comb tooth size, which has D1 possible values, and the resource location has D2 possible values. A second correspondence exists between the comb tooth size values ​​and the resource location values. Here, D1 and D2 are integers greater than or equal to 1, and the second correspondence is determined based on protocol predefined information or network configuration information.

[0344] In some embodiments, determining the resource position of the transmission resource in the second transmission resource based on the comb tooth size includes at least one of the following: determining the resource start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size; determining the resource end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size; and determining the resource size of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size.

[0345] In some embodiments, determining the resource start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size includes at least one of the following: determining the time domain start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size; determining the frequency domain start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size; and determining the logical resource unit start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size.

[0346] In some embodiments, determining the resource end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size includes at least one of the following: determining the time domain end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size; determining the frequency domain end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size; and determining the logical resource unit end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size.

[0347] In some embodiments, determining the resource size of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size includes at least one of the following: determining the number of time-domain units of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size; determining the number of frequency-domain units of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size; and determining the number of logical resource units of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth size.

[0348] In some embodiments, the resource location of the transmission resource corresponding to the transmission content in the second transmission resource is determined based on the comb tooth size among multiple or multiple sets of second candidate parameter values. The second candidate parameter corresponds to one resource location or a set of resource locations.

[0349] 3.1.1 For the second candidate parameter, there is a corresponding resource location.

[0350] In some embodiments, the value of the second candidate parameter may correspond to the value of a transmission parameter. Optionally, based on the comb tooth size among multiple values ​​of the second candidate parameter, the resource position of the transmission resource corresponding to the transmission content in the second transmission resource is determined.

[0351] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0352] For example, taking the resource location as the time-domain start position. Here, the time-domain start position refers to the starting position of the transmitted content on the second transmission resource in the time domain dimension. Optionally, the value of the time-domain start position of the transmission resource corresponding to the transmitted content in the second transmission resource is determined based on the comb tooth size. Different comb tooth sizes correspond to different values ​​of the time-domain start position. The relationship between the network device configuration comb tooth size and the value of the time-domain start position is shown in Table 13.

[0353] Table 13

[0354] For example, the first information includes the comb tooth size, which is determined based on the resource element interval between two adjacent transmission resources on an OFDM symbol in the first transmission resource used to map the first indication information. Taking an example where the comb tooth size includes four values, and the time-domain start position on the second transmission resource (the time-domain start position corresponding to the transmission content on the second transmission resource) also includes four time-domain start positions. There is a second correspondence between the values ​​of the comb tooth size and the values ​​of the time-domain start positions. Optionally, when the comb tooth size is the first comb tooth size, it corresponds to the first time-domain start position on the second transmission resource; when the comb tooth size is the second comb tooth size, it corresponds to the second time-domain start position on the second transmission resource; when the comb tooth size is the third comb tooth size, it corresponds to the third time-domain start position on the second transmission resource; and when the comb tooth size is the fourth comb tooth size, it corresponds to the fourth time-domain start position on the second transmission resource.

[0355] For example, when the first comb tooth size is 1, it is used to indicate the time-domain start position A in the second transmission resource. As another example, when the second comb tooth size is 2, it is used to indicate the time-domain start position B in the second transmission resource. As another example, when the third comb tooth size is 4, it is used to indicate the time-domain start position C in the second transmission resource. As another example, when the fourth comb tooth size is 6, it is used to indicate the time-domain start position D in the second transmission resource.

[0356] It should be noted that Table 13 above is merely an exemplary illustration of the second correspondence between the comb tooth size and the time-domain start position in the second transmission resource. The method implemented in this application is not limited to the correspondence in Table 13. In some embodiments, the second correspondence of the network configuration only includes a portion of the contents of the table above, such as only any two rows in the table above; in some embodiments, the second correspondence of the network configuration includes K comb tooth sizes, and the corresponding time-domain start position values ​​in the second transmission resource are also K, where K is an integer greater than or equal to 1.

[0357] 3.1.2 For the second candidate parameter, a set of resource locations is defined.

[0358] In some embodiments, the value of the second candidate parameter may correspond to a set of transmission parameter values. Optionally, based on the comb tooth size, the resource position of the transmission resource corresponding to the transmission content in the second transmission resource is determined from multiple sets of second candidate parameter values.

[0359] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0360] For example, consider resource locations as the time-domain start position and the number of time-domain units. The time-domain start position refers to the starting position of the transmitted content on the second transmission resource in the time domain dimension. The number of time-domain units refers to the number of time units occupied by the transmitted content on the second transmission resource in the time domain dimension. Optionally, the value of the time-domain start position and the value of the number of time-domain units are determined based on the comb tooth size. Different comb tooth sizes correspond to different values ​​of the time-domain start position and different values ​​of the number of time-domain units. A second correspondence between the comb tooth size configured in the network device and a set of resource locations (time-domain start position and number of time-domain units) is shown in Table 14.

[0361] Table 14

[0362] For example, the first information includes the comb tooth size. Taking an example where the comb tooth size includes four values, and taking an example where the time-domain start position on the second transmission resource includes four time-domain start positions, the values ​​of the comb tooth size have a second correspondence with the values ​​of the time-domain start position and the number of time-domain units. Optionally, when the comb tooth size is a first comb tooth size, it corresponds to a first time-domain start position and a first time-domain unit number on the second transmission resource; when the comb tooth size is a second comb tooth size, it corresponds to a second time-domain start position and a second time-domain unit number on the second transmission resource; when the comb tooth size is a third comb tooth size, it corresponds to a third time-domain start position and a third time-domain unit number on the second transmission resource; and when the comb tooth size is a fourth comb tooth size, it corresponds to a fourth time-domain start position and a fourth time-domain unit number on the second transmission resource.

[0363] For example, when the first comb tooth size is 1, it indicates the time-domain start position A in the second transmission resource and indicates that the number of time-domain units is 1. As another example, when the second comb tooth size is 2, it is used to indicate the time-domain start position B in the second transmission resource and indicates that the number of time-domain units is 2. As another example, when the third comb tooth size is 4, it is used to indicate the time-domain start position C in the second transmission resource and indicates that the number of time-domain units is 3. As another example, when the fourth comb tooth size is 6, it is used to indicate the time-domain start position D in the second transmission resource and indicates that the number of time-domain units is 4.

[0364] It should be noted that Table 14 above is merely an exemplary illustration of the second correspondence between the comb tooth size values ​​and the values ​​of the time-domain start position and the number of time-domain units in the second transmission resource. The method implemented in this application is not limited to the correspondence in Table 14. In some embodiments, the second correspondence of the network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the second correspondence of the network configuration includes K comb tooth sizes, and the corresponding values ​​of the time-domain start position and the number of time-domain units in the second transmission resource are also K, where K is an integer greater than or equal to 1.

[0365] 3.2 Determining the resource location of transmission resources in the second transmission resource based on comb tooth offset

[0366] In some embodiments, the first information associated with the first indication information includes a comb tooth offset, and the transmission information on the second transmission resource includes the resource position of the transmission resource within the second transmission resource. Optionally, the resource position of the transmission resource within the second transmission resource is determined based on the comb tooth offset. In some embodiments, the first information includes the comb tooth offset, the comb tooth offset having E1 values, the resource position having E2 values, and a second correspondence between the values ​​of the comb tooth offset and the values ​​of the resource position. Here, E1 and E2 are integers greater than or equal to 1, and the second correspondence is determined based on protocol predefined information or network configuration information.

[0367] In some embodiments, determining the resource position of the transmission resource in the second transmission resource based on the comb tooth offset includes at least one of the following: determining the resource start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset; determining the resource end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset; and determining the resource size of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset.

[0368] In some embodiments, determining the resource start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset includes at least one of the following: determining the time domain start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset; determining the frequency domain start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset; and determining the logical resource unit start position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset.

[0369] In some embodiments, determining the end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset includes at least one of the following: determining the time domain end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset; determining the frequency domain end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset; and determining the logical resource unit end position of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset.

[0370] In some embodiments, determining the resource size of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset includes at least one of the following: determining the number of time-domain units of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset; determining the number of frequency-domain units of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset; and determining the number of logical resource units of the transmission resource corresponding to the transmission content in the second transmission resource based on the comb tooth offset.

[0371] In some embodiments, the resource location of the transmission resource corresponding to the transmission content in the second transmission resource is determined based on the comb tooth offset among multiple or multiple sets of second candidate parameter values. The second candidate parameter corresponds to one resource location or a set of resource locations.

[0372] 3.2.1 For the second candidate parameter, there is a corresponding resource location.

[0373] In some embodiments, the value of the second candidate parameter may correspond to the value of a transmission parameter. Optionally, based on the comb offset among multiple values ​​of the second candidate parameter, the resource position of the transmission resource corresponding to the transmission content in the second transmission resource is determined.

[0374] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0375] For example, taking the resource location as the frequency domain starting position. Here, the frequency domain starting position refers to the starting position of the transmitted content on the second transmission resource in the frequency domain dimension. Optionally, the value of the frequency domain starting position of the transmission resource corresponding to the transmitted content in the second transmission resource is determined based on the comb offset. Different comb offsets correspond to different values ​​of the frequency domain starting position. The relationship between the network device configuration comb offset and the value of the frequency domain starting position is shown in Table 15.

[0376] Table 15

[0377] For example, the first information includes a comb tooth offset, which indicates the offset of the comb tooth resources occupied when the first indication information is mapped on the first OFDM symbol in the first transmission resource. Taking an example where the comb tooth offset includes four values, and taking an example where the frequency domain start position on the second transmission resource includes four frequency domain start positions, there is a correspondence between the values ​​of the comb tooth offset and the values ​​of the frequency domain start positions on the second transmission resource. Optionally, when the comb tooth offset is the first comb tooth offset, it corresponds to the first frequency domain start position on the second transmission resource; when the comb tooth offset is the second comb tooth offset, it corresponds to the second frequency domain start position on the second transmission resource; when the comb tooth offset is the third comb tooth offset, it corresponds to the third frequency domain start position on the second transmission resource; and when the comb tooth offset is the fourth comb tooth offset, it corresponds to the fourth frequency domain start position on the second transmission resource.

[0378] The following explanation uses the example of mapping the first indication information onto a first transmission resource with a comb tooth size of 4, specifically, taking an OFDM symbol in the first transmission resource where the interval between two adjacent transmission resources used to map the first indication information is 4. For example, when the first comb tooth offset is 0, it indicates the frequency domain start position 'a' in the second transmission resource. As another example, when the second comb tooth offset is 1, it indicates the frequency domain start position 'b' in the second transmission resource. As another example, when the third comb tooth offset is 2, it indicates the frequency domain start position 'c' in the second transmission resource. As another example, when the fourth comb tooth offset is 3, it indicates the frequency domain start position 'd' in the second transmission resource.

[0379] It should be noted that Table 15 above is merely an exemplary illustration of the second correspondence between the comb tooth offset and the value of the frequency domain start position in the second transmission resource. The method implemented in this application is not limited to the correspondence in Table 15. In some embodiments, the second correspondence of the network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the second correspondence of the network configuration includes K comb tooth offsets, and the corresponding values ​​of the frequency domain start positions in the second transmission resource are also K, where K is an integer greater than or equal to 1.

[0380] 3.2.2 For the second candidate parameter, a set of resource locations is defined.

[0381] In some embodiments, the value of the second candidate parameter may correspond to a set of transmission parameter values. Optionally, based on the comb offset, the resource position of the transmission resource corresponding to the transmission content in the second transmission resource is determined from multiple sets of second candidate parameter values.

[0382] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0383] For example, consider the resource location as the frequency domain start position and the number of frequency domain units. The frequency domain start position refers to the starting position of the transmitted content on the second transmission resource in the frequency domain dimension. The number of frequency domain units refers to the number of frequency domain units occupied by the transmitted content on the second transmission resource in the frequency domain dimension. Optionally, the value of the frequency domain start position and the value of the number of frequency domain units are determined based on the comb offset. Different comb offsets correspond to different values ​​of the frequency domain start position and different values ​​of the number of frequency domain units. The second correspondence between the network device configuration comb offset and a set of resource locations (frequency domain start position and number of frequency domain units) is shown in Table 16.

[0384] Table 16

[0385] For example, the first information includes a comb tooth offset. Taking an example where the comb tooth offset includes four values, and taking an example where the frequency domain start position on the second transmission resource includes four frequency domain start positions, there is a correspondence between the values ​​of the comb tooth offset and the values ​​of the frequency domain start positions on the second transmission resource. Optionally, when the comb tooth offset is a first comb tooth offset, it corresponds to the first frequency domain start position and the number of first frequency domain units on the second transmission resource; when the comb tooth offset is a second comb tooth offset, it corresponds to the second frequency domain start position and the number of second frequency domain units on the second transmission resource; when the comb tooth offset is a third comb tooth offset, it corresponds to the third frequency domain start position and the number of third frequency domain units on the second transmission resource; and when the comb tooth offset is a fourth comb tooth offset, it corresponds to the fourth frequency domain start position and the number of fourth frequency domain units on the second transmission resource.

[0386] The following explanation uses the example of mapping the first indication information onto the first transmission resource with a comb tooth size of 4, that is, taking an interval of 4 between two adjacent transmission resources used to map the first indication information on an OFDM symbol in the first transmission resource. For example, when the first comb tooth offset is 0, it is used to indicate the frequency domain start position 'a' in the second transmission resource and the number of frequency domain units is 1. As another example, when the second comb tooth offset is 1, it is used to indicate the frequency domain start position 'b' in the second transmission resource and the number of frequency domain units is 2. As another example, when the third comb tooth offset is 2, it is used to indicate the frequency domain start position 'c' in the second transmission resource and the number of frequency domain units is 3. As another example, when the fourth comb tooth offset is 3, it is used to indicate the frequency domain start position 'd' in the second transmission resource and the number of frequency domain units is 4.

[0387] It should be noted that Table 16 above is merely an exemplary illustration of the second correspondence between the values ​​of the comb tooth offset and the values ​​of the frequency domain start position and the number of frequency domain units in the second transmission resource. The method implemented in this application is not limited to the correspondence in Table 16. In some embodiments, the second correspondence of the network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the second correspondence of the network configuration includes K comb tooth offsets, and the corresponding values ​​of the frequency domain start position and the number of frequency domain units in the second transmission resource are also K, where K is an integer greater than or equal to 1.

[0388] 3.3 Determine the resource location of the transmission resource in the second transmission resource based on the combination of comb tooth size and comb tooth offset.

[0389] In some embodiments, the first information associated with the first indication information includes the comb tooth size and comb tooth offset, and the transmission information on the second transmission resource includes the resource location of the transmission resource within the second transmission resource. Optionally, the resource location of the transmission resource within the second transmission resource is determined based on a combination of the comb tooth size and comb tooth offset.

[0390] In some embodiments, the first information includes the comb tooth size and the comb tooth offset. The combined values ​​of the comb tooth size and the comb tooth offset include F1 values, and the resource location values ​​include F2 values. There is a second correspondence between the combined values ​​of the comb tooth size and the comb tooth offset and the resource location values. Here, F1 and F2 are integers greater than or equal to 1, and the second correspondence is determined based on protocol predefined information or network configuration information.

[0395] In some embodiments, based on a combination of comb tooth size and comb tooth offset, the resource location of the transmission resource corresponding to the transmission content within the second transmission resource is determined from among multiple or multiple sets of second candidate parameter values. The second candidate parameter corresponds to one resource location or a set of resource locations.

[0396] 3.3.1 For the second candidate parameter, there is a corresponding resource location.

[0397] In some embodiments, the value of the second candidate parameter may correspond to the value of a transmission parameter. Optionally, based on the combination of comb tooth size and comb tooth offset, the resource position of the transmission resource corresponding to the transmission content in the second transmission resource is determined from multiple second candidate parameter values.

[0398] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0399] For example, consider the resource location as the time-domain end position. Here, the time-domain start position refers to the end position of the transmitted content on the second transmission resource in the time domain dimension. Optionally, the time-domain end position of the transmission resource corresponding to the transmitted content in the second transmission resource is determined based on the combination of comb tooth size and comb tooth offset. Different combinations of comb tooth size and comb tooth offset correspond to different values ​​of the time-domain end position. The relationship between the combination of comb tooth size and comb tooth offset configured in the network device and the time-domain end position is shown in Table 17.

[0400] Table 17

[0401] For example, the first information includes a combination of comb tooth size and comb tooth offset. Taking four combinations of comb tooth size and comb tooth offset as an example, and four time-domain end positions on the second transmission resource as an example, the combined values ​​of the comb tooth size and comb tooth offset have a second correspondence with the values ​​of the time-domain end positions. Optionally, when the combination of comb tooth size and comb tooth offset is a first combination, it corresponds to a first time-domain end position on the second transmission resource; when the combination of comb tooth size and comb tooth offset is a second combination, it corresponds to a second time-domain end position on the second transmission resource; when the combination of comb tooth size and comb tooth offset is a third combination, it corresponds to a third time-domain end position on the second transmission resource; and when the combination of comb tooth size and comb tooth offset is a fourth combination, it corresponds to a fourth time-domain end position on the second transmission resource.

[0402] For example, when the first combination is a combination of comb tooth size 4 and comb tooth offset 0, it is used to indicate the time domain end position A in the second transmission resource. As another example, when the second combination is a combination of comb tooth size 4 and comb tooth offset 2, it is used to indicate the time domain end position B in the second transmission resource. As another example, when the third combination is a combination of comb tooth size 2 and comb tooth offset 0, it is used to indicate the time domain end position C in the second transmission resource. As another example, when the fourth combination is a combination of comb tooth size 2 and comb tooth offset 1, it is used to indicate the time domain end position D in the second transmission resource.

[0403] It should be noted that Table 17 above is merely an exemplary illustration of the second correspondence between the combined values ​​of comb tooth size and comb tooth offset and the values ​​of the time-domain end positions. The method implemented in this application is not limited to the correspondence in Table 17. In some embodiments, the first correspondence of network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the first correspondence of network configuration includes K combinations of comb tooth size and comb tooth offset, and the corresponding values ​​of the time-domain end positions are also K, where K is an integer greater than or equal to 1.

[0404] 3.3.2 For the second candidate parameter, a set of resource locations is defined.

[0405] In some embodiments, the value of the second candidate parameter may correspond to a set of transmission parameter values. Optionally, based on a combination of comb tooth size and comb tooth offset, the resource position of the transmission resource corresponding to the transmission content in the second transmission resource is determined from multiple second candidate parameter values.

[0406] The following are some examples, but it is impossible to exhaust all possible combinations. The examples below are only illustrative.

[0407] For example, consider resource locations as the time-domain end position and the number of time-domain units. The time-domain end position refers to the end position of the transmitted content on the second transmission resource in the time domain dimension. The number of time-domain units refers to the number of time units occupied by the transmitted content on the second transmission resource in the time domain dimension. Optionally, the value of the time-domain end position and the value of the number of time-domain units are determined based on a combination of comb tooth size and comb tooth offset. Different combinations of comb tooth size and comb tooth offset correspond to different values ​​of the time-domain end position and different values ​​of the number of time-domain units. The second correspondence between the combination of comb tooth size and comb tooth offset configured in the network device and a set of resource locations (time-domain end position and number of time-domain units) is shown in Table 18.

[0408] Table 18

[0409] For example, the first information includes a combination of comb tooth size and comb tooth offset. Taking the combination of comb tooth size and comb tooth offset as having four combinations as an example, the combined values ​​of comb tooth size and comb tooth offset have a second correspondence with the values ​​of the time domain end position and the number of time domain units. Optionally, when the combination of comb tooth size and comb tooth offset is the first combination, it corresponds to the first time domain end position and the first number of time domain units on the second transmission resource; when the comb tooth size is the second comb tooth size, it corresponds to the second time domain end position and the second number of time domain units on the second transmission resource; when the comb tooth size is the third comb tooth size, it corresponds to the third time domain end position and the third number of time domain units on the second transmission resource; and when the comb tooth size is the fourth comb tooth size, it corresponds to the fourth time domain end position and the fourth number of time domain units on the second transmission resource.

[0410] For example, when the first combination is a combination of a comb tooth size of 4 and a comb tooth offset of 0, it is used to indicate the time-domain end position A in the second transmission resource and to indicate that the number of time-domain units is 1. As another example, when the second combination is a combination of a comb tooth size of 4 and a comb tooth offset of 2, it is used to indicate the time-domain end position B in the second transmission resource and to indicate that the number of time-domain units is 2. As another example, when the third combination is a combination of a comb tooth size of 2 and a comb tooth offset of 0, it is used to indicate the time-domain end position C in the second transmission resource and to indicate that the number of time-domain units is 3. As another example, when the fourth combination is a combination of a comb tooth size of 2 and a comb tooth offset of 1, it is used to indicate the time-domain end position D in the second transmission resource and to indicate that the number of time-domain units is 4.

[0411] It should be noted that Table 18 above is merely an exemplary illustration of the second correspondence between the combined values ​​of comb tooth size and comb tooth offset and the values ​​of the time-domain end position and the number of time-domain units in the second transmission resource. The method implemented in this application is not limited to the correspondence in Table 14. In some embodiments, the second correspondence of network configuration only includes part of the content in the table above, such as only including any two rows in the table above; in some embodiments, the second correspondence of network configuration includes K combinations of comb tooth size and comb tooth offset, and the corresponding values ​​of the time-domain end position and the number of time-domain units in the second transmission resource are also K, where K is an integer greater than or equal to 1.

[0412] Scenario 2: Based on the first information associated with the first indication information, at least two types of transmission information are indicated on the second transmission resource.

[0413] In some embodiments, the first information associated with the first indication information is used to indicate at least two types of transmission information on the second transmission resource. The at least two types of transmission information include transmission content in the second transmission resource; transmission parameters corresponding to the transmission content in the second transmission resource; and at least two resource locations of the transmission resource in the second transmission resource.

[0421] 1.1 Regarding Transmitted Information One and Transmitted Information Two

[0422] In some embodiments, first information associated with first indication information indicates two types of transmission information on the second transmission resource. These two types of transmission information include transmission content in the second transmission resource and transmission parameters corresponding to the transmission content in the second transmission resource. The transmission content in the second transmission resource is determined based on the first information associated with the first indication information, and the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource are also determined.

[0423] In some embodiments, the first information includes the comb tooth size, the transmission content in the second transmission resource is determined based on the comb tooth size, and the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource are determined. Optionally, there is an association or correspondence between the comb tooth size, the transmission content in the second transmission resource, and the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource, and this association or correspondence is determined based on protocol predefined information or network configuration information.

[0424] For example, taking the transmission content in the second transmission resource as DCI transmitted on the second transmission resource, and the transmission parameters corresponding to the transmission content in the second transmission resource as the aggregation level corresponding to the DCI, as an example. Referring to Figure 12, the first transmission resource includes one OFDM symbol, and the number of resource units corresponding to it in the frequency domain is 36. The comb tooth size is determined based on the resource unit interval between two adjacent transmission resources on one OFDM symbol in the first transmission resource used to map the first indication information. As shown in part (a) of Figure 12, when the comb tooth size is 1, that is, when the resource unit interval between two adjacent transmission resources on one OFDM symbol in the first transmission resource used to map the first indication information is 1, it is used to indicate the transmission of DCI on the second transmission resource, and the aggregation level corresponding to the DCI is 1. As shown in part (b) of Figure 12, when the comb tooth size is 2, that is, when the resource unit interval between two adjacent transmission resources on one OFDM symbol in the first transmission resource used to map the first indication information is 2, it is used to indicate the transmission of DCI on the second transmission resource, and the aggregation level corresponding to the DCI is 2. As shown in part (c) of Figure 12, when the comb tooth size is 3, that is, when the resource unit interval between two adjacent transmission resources used to map the first indication information on an OFDM symbol in the first transmission resource is 3, it is used to indicate the transmission of DCI on the second transmission resource, and the aggregation level corresponding to the indicated DCI is 4. As shown in part (d) of Figure 12, when the comb tooth size is 4, that is, when the resource unit interval between two adjacent transmission resources used to map the first indication information on an OFDM symbol in the first transmission resource is 4, it is used to indicate the transmission of DCI on the second transmission resource, and the aggregation level corresponding to the indicated DCI is 8.

[0425] In some embodiments, the first information includes a comb tooth offset, the transmission content in the second transmission resource is determined based on the comb tooth offset, and the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource are determined. Optionally, there is an association or correspondence between the comb tooth offset, the transmission content in the second transmission resource, and the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource, and this association or correspondence is determined based on protocol predefined information or network configuration information.

[0426] For example, taking the transmission content in the second transmission resource as the uplink and downlink data transmitted on the second transmission resource, and the transmission parameters corresponding to the transmission content in the second transmission resource as the modulation scheme corresponding to the downlink data, as an example. Referring to Figure 13, the first transmission resource includes one OFDM symbol, and the number of resource units corresponding to it in the frequency domain is 36. Taking the first indication information mapped onto the first transmission resource with a comb tooth size of 4 as an example, as shown in part (a) of Figure 13, when the comb tooth offset is 0, it is used to indicate that the uplink and downlink data are transmitted on the second transmission resource, and to indicate that the modulation scheme corresponding to the downlink data is QPSK modulation. As shown in part (b) of Figure 13, when the comb tooth offset is 1, it is used to indicate that the uplink and downlink data are transmitted on the second transmission resource, and to indicate that the modulation scheme corresponding to the downlink data is 16QAM modulation. As shown in part (c) of Figure 13, when the comb tooth offset is 1, it is used to indicate that the uplink and downlink data are transmitted on the second transmission resource, and to indicate that the modulation scheme corresponding to the downlink data is 64QAM modulation. As shown in part (d) of Figure 13, when the comb offset is 1, it is used to indicate the uplink and downlink data transmission on the second transmission resource, and to indicate that the modulation mode corresponding to the downlink data is 256QAM modulation.

[0427] In some embodiments, the first information includes the comb tooth size and comb tooth offset. Based on the combination of the comb tooth size and comb tooth offset, the transmission content in the second transmission resource is determined, and the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource are also determined. Optionally, there is an association or correspondence between the combination of the comb tooth size and comb tooth offset and the transmission content in the second transmission resource and the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource. This association or correspondence is determined based on protocol predefined information or network configuration information.

[0428] In some embodiments, the transmission content in the second transmission resource is determined based on a combination of comb tooth size and comb tooth offset, and the values ​​of transmission parameters corresponding to the transmission content in the second transmission resource are also determined. Optionally, the transmission content in the second transmission resource is determined by the comb tooth size in the combination, with different comb tooth sizes corresponding to different transmission contents in the second transmission resource; the values ​​of transmission parameters corresponding to the transmission content in the second transmission resource are determined by the comb tooth offset in the combination, with different comb tooth offsets corresponding to different values ​​of transmission parameters corresponding to the transmission content in the second transmission resource. This application does not limit this approach.

[0429] For example, the transmission content in the second transmission resource is determined by the comb tooth size in the combination, and the transmission parameter value corresponding to the transmission content in the second transmission resource is determined by the comb tooth offset in the combination. Referring to Figure 14, the first transmission resource includes one OFDM symbol, and the number of resource units corresponding to it in the frequency domain is 36. As shown in parts (a) and (b) of Figure 14, when the comb tooth size is 2, it indicates that the transmission content in the second transmission resource is downlink data; when the comb tooth offset is 0, it indicates that the modulation mode corresponding to the downlink data is QPSK modulation; and when the comb tooth offset is 1, it indicates that the modulation mode corresponding to the downlink data is 16QAM modulation. As shown in (c), (d), (e), and (f) of Figure 14, when the comb tooth size is 4, it indicates that the transmission content in the second transmission resource is DCI; when the comb tooth offset is 0, it indicates that the aggregation level corresponding to DCI is 1; when the comb tooth offset is 1, it indicates that the aggregation level corresponding to DCI is 2; when the comb tooth offset is 2, it indicates that the aggregation level corresponding to DCI is 4; and when the comb tooth offset is 3, it indicates that the aggregation level corresponding to DCI is 8.

[0432] In some embodiments, first information associated with first indication information indicates two types of transmission information on the second transmission resource. These two types of transmission information include transmission content within the second transmission resource and the resource location of the transmission resource within the second transmission resource. The transmission content within the second transmission resource and the resource location of the transmission resource within the second transmission resource are determined based on the first information associated with the first indication information.

Referring to Figure 15, the first transmission resource includes one OFDM symbol, and the number of resource units corresponding to it in the frequency domain is 36. The comb tooth size is determined based on the resource unit interval between two adjacent transmission resources used to map the first indication information on one OFDM symbol in the first transmission resource. As shown in part (a) of Figure 15, when the comb tooth size is 1, it is used to indicate the transmission of DCI on the second transmission resource and to indicate the time-domain start position A in the second transmission resource. As shown in part (b) of Figure 15, when the comb tooth size is 2, it is used to indicate the transmission of DCI on the second transmission resource and to indicate the time-domain start position B in the second transmission resource. As shown in part (c) of Figure 15, when the comb tooth size is 3, it is used to indicate the transmission of DCI on the second transmission resource and to indicate the time-domain start position C in the second transmission resource.

As shown in part (c) of Figure 16, when the comb tooth offset is 1, it is used to indicate the uplink and downlink data transmission on the second transmission resource, and to indicate the frequency domain start position c in the second transmission resource. As shown in part (d) of Figure 16, when the comb offset is 1, it is used to indicate the uplink and downlink data transmission on the second transmission resource, and to indicate the frequency domain start position d in the second transmission resource.

Optionally, there is an association or correspondence between the combination of comb tooth size and comb tooth offset and the transmission content in the second transmission resource and the resource location of the transmission resource in the second transmission resource. This association or correspondence is determined based on protocol predefined information or network configuration information.

[0438] In some embodiments, the transmission content in the second transmission resource and the resource position of the transmission resource in the second transmission resource are determined based on a combination of comb tooth size and comb tooth offset. Optionally, the transmission content in the second transmission resource is determined by the comb tooth size in the combination, with different comb tooth sizes corresponding to different transmission contents in the second transmission resource; the resource position of the transmission resource in the second transmission resource is determined by the comb tooth offset in the combination, with different comb tooth offsets corresponding to different resource positions in the second transmission resource.

[0452] In some embodiments, three types of transmission information on the second transmission resource are indicated based on the first information associated with the first indication information. These three types of transmission information include transmission content in the second transmission resource, transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource. The transmission content in the second transmission resource is determined based on the first information associated with the first indication information, as are the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0453] In some embodiments, the first information associated with the first indication information includes the comb tooth size, determining the transmission content in the second transmission resource based on the comb tooth size, determining the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource, and determining the resource location of the transmission resource in the second transmission resource.

This association or correspondence is determined based on protocol predefined information or network configuration information.

[0454] For example, taking the transmission content in the second transmission resource as the DCI transmitted on the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource as the aggregation level corresponding to the DCI, and the resource position of the transmission resource corresponding to the DCI in the second transmission resource as the time domain start position as an example. Referring to Figure 18, the first transmission resource includes one OFDM symbol, the number of resource units corresponding to it in the frequency domain is 36, and the comb tooth size is determined based on the resource unit interval between two adjacent transmission resources used to map the first indication information on one OFDM symbol in the first transmission resource.

As shown in part (b) of Figure 18, when the comb tooth size is 2, it is used to indicate the transmission of DCI on the second transmission resource, and to indicate that the aggregation level corresponding to the DCI is 2, and to indicate the time domain start position B in the second transmission resource. As shown in part (c) of Figure 18, when the comb tooth size is 3, it is used to indicate the transmission of DCI on the second transmission resource, the aggregation level corresponding to the DCI is 4, and the time domain start position C in the second transmission resource. As shown in part (d) of Figure 18, when the comb tooth size is 4, it is used to indicate the transmission of DCI on the second transmission resource, the aggregation level corresponding to the DCI is 8, and the time domain start position D in the second transmission resource.

[0455] In some embodiments, the first information associated with the first indication information includes a comb tooth offset, determining the transmission content in the second transmission resource based on the comb tooth offset, determining the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource, and determining the resource position of the transmission resource in the second transmission resource. Optionally, there is an association or correspondence between the comb tooth offset, the transmission content in the second transmission resource, the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource position of the transmission resource in the second transmission resource. This association or correspondence is determined based on protocol predefined information or network configuration information.

[0456] For example, taking the transmission content in the second transmission resource as the uplink and downlink data transmitted on the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource as the modulation scheme corresponding to the downlink data, and the resource position of the transmission resource corresponding to the downlink data in the second transmission resource as the frequency domain start position, as an example. Referring to Figure 19, the first transmission resource includes one OFDM symbol, and the number of resource units corresponding to it in the frequency domain is 36. Taking the first indication information mapped onto the first transmission resource with a comb tooth size of 4 as an example, as shown in part (a) of Figure 19, when the comb tooth offset is 0, it is used to indicate that the downlink data is transmitted on the second transmission resource, and to indicate that the modulation scheme corresponding to the downlink data is QPSK modulation, and to indicate the frequency domain start position a in the second transmission resource. As shown in part (b) of Figure 19, when the comb tooth offset is 1, it is used to indicate that the downlink data is transmitted on the second transmission resource, and to indicate that the modulation scheme corresponding to the downlink data is 16QAM modulation, and to indicate the frequency domain start position b in the second transmission resource. As shown in part (c) of Figure 19, when the comb tooth offset is 1, it is used to indicate that downlink data is transmitted on the second transmission resource, that the modulation scheme corresponding to the downlink data is 64QAM modulation, and that the frequency domain start position c in the second transmission resource is indicated. As shown in part (d) of Figure 19, when the comb tooth offset is 1, it is used to indicate that downlink data is transmitted on the second transmission resource, that the modulation scheme corresponding to the downlink data is 256QAM modulation, and that the frequency domain start position d in the second transmission resource is indicated.

[0457] In some embodiments, the first information associated with the first indication information includes a combination of comb tooth size and comb tooth offset. Based on the combination of comb tooth size and comb tooth offset, the transmission content in the second transmission resource is determined, as are the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource and the resource position of the transmission resource in the second transmission resource. Optionally, there is an association or correspondence between the combination of comb tooth size and comb tooth offset, the transmission content in the second transmission resource, the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource position of the transmission resource in the second transmission resource. This association or correspondence is determined based on protocol predefined information or network configuration information.

[0458] For example, the transmission content in the second transmission resource is determined by the comb tooth size in the combination, and the values ​​of the transmission parameters corresponding to the transmission content in the second transmission resource and the resource position of the transmission resource in the second transmission resource are determined by the comb tooth offset in the combination. Referring to Figure 20, the first transmission resource includes one OFDM symbol, and the number of resource units corresponding to it in the frequency domain is 36. As shown in parts (a) and (b) of Figure 20, when the comb tooth size is 2, it indicates that the transmission content in the second transmission resource is downlink data; when the comb tooth offset is 0, it indicates that the modulation mode corresponding to the downlink data is QPSK modulation, and it also indicates the frequency domain start position a in the second transmission resource; when the comb tooth offset is 1, it indicates that the modulation mode corresponding to the downlink data is 16QAM modulation, and it also indicates the frequency domain start position b in the second transmission resource. As shown in parts (c), (d), (e), and (f) of Figure 20, when the comb tooth size is 4, it indicates that the transmitted content in the second transmission resource is DCI; when the comb tooth offset is 0, it indicates that the aggregation level corresponding to DCI is 1, and it indicates the time domain start position A in the second transmission resource; when the comb tooth offset is 1, it indicates that the aggregation level corresponding to DCI is 2, and it indicates the time domain start position B in the second transmission resource; when the comb tooth offset is 2, it indicates that the aggregation level corresponding to DCI is 4, and it indicates the time domain start position C in the second transmission resource; when the comb tooth offset is 3, it indicates that the aggregation level corresponding to DCI is 8, and it indicates the time domain start position D in the second transmission resource.

[0459] In one possible implementation, the sequence carrying first indication information is used to indicate the transmission content in the second transmission resource, the first information is used to indicate the transmission parameters corresponding to the transmission content in the second transmission resource, and / or, to indicate the resource position of the transmission resource in the second transmission resource. Optionally, the sequence carrying first indication information is used to determine the transmission content in the second transmission resource, and the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined based on the first information; or, the sequence carrying first indication information is used to determine the transmission content in the second transmission resource, and the resource position of the transmission resource in the second transmission resource is determined based on the first information; or, the sequence carrying first indication information is used to determine the transmission content in the second transmission resource, the value of the transmission parameter corresponding to the transmission content in the second transmission resource is determined based on the first information, and the resource position of the transmission resource in the second transmission resource is determined.

[0460] For example, the transmission content in the second transmission resource is determined based on the sequence, the transmission parameter values ​​corresponding to the transmission content are determined based on the comb tooth size, and the resource position of the transmission resource in the second transmission resource is determined based on the comb tooth offset. Referring to Figure 21, the first transmission resource includes one OFDM symbol, and the number of resource units corresponding to it in the frequency domain is 36. When the first indication information is carried based on the first sequence, it is used to indicate that the transmission content on the second transmission resource is DCI. Taking the total number of resources in the second transmission resource corresponding to 8 CCE sizes as an example, as shown in parts (a) and (b) of Figure 21, when the comb tooth size is 2, the number of CCEs corresponding to the indicated DCI is 4 CCEs; when the comb tooth offset is 0, the logical unit starting position of the indicated DCI in the second transmission resource is CCE index 0; when the comb tooth offset is 0, the logical unit starting position of the indicated DCI in the second transmission resource is CCE index 4. As shown in parts (c), (d), (e), and (f) of Figure 21, when the comb tooth size is 4, the number of CCEs corresponding to the DCI is 2CCEs; when the comb tooth offset is 0, the starting position of the logical unit of the DCI in the second transmission resource is CCE index 0; when the comb tooth offset is 1, the starting position of the logical unit of the DCI in the second transmission resource is CCE index 2; when the comb tooth offset is 2, the starting position of the logical unit of the DCI in the second transmission resource is CCE index 4; and when the comb tooth offset is 3, the starting position of the logical unit of the DCI in the second transmission resource is CCE index 6.

[0461] Figure 22 shows a structural block diagram of an information indicating device provided in an exemplary embodiment of this application. This information indicating device can be implemented as a terminal device, or as part of a terminal device, through software, hardware, or a combination of both. The information indicating device includes: an acquisition module 1310.

[0462] The acquisition module 1310 is used to acquire first indication information on the first transmission resource, and the first information associated with the first indication information is used to indicate the transmission information on the second transmission resource.

[0463] The first transmission resource and the second transmission resource are transmission resources configured by the network device for the acquisition module 1310. Optionally, the transmission resources include, but are not limited to, resources in at least one dimension of time domain resources, frequency domain resources, code domain resources, and spatial domain resources.

[0464] In some embodiments, the acquisition module 1310 acquires the first indication information on the first transmission resource. This can also be understood as the acquisition module 1310 receiving the first indication information on the first transmission resource, or monitoring or detecting the first indication information on the first transmission resource. Optionally, the first transmission resource is used to transmit the first indication information, which is carried based on a sequence or information bits. The first information associated with the first indication information is used to indicate transmission information on the second transmission resource. Optionally, the second transmission resource is used for downlink transmission, and the second transmission resource is used to transmit DCI and / or downlink data.

[0465] In some embodiments, the first information is related information that the first indication information is mapped onto the first transmission resource in a comb-like manner. Optionally, the first information includes at least one of comb size and comb offset. For example, the first information includes comb size, or the first information includes comb offset, or the first information includes both comb size and comb offset. The resources for transmitting the first indication information are arranged in a comb-like pattern within the first transmission resource. The first transmission resource can be considered as a set of comb-like resources, or a set of transmission resources arranged in a comb-like pattern, or a set of equally spaced transmission resources, or the first transmission resource corresponds to a frequency-continuous resource, and the resources for transmitting the first indication information are distributed in a comb-like pattern within the first transmission resource.

[0466] In some embodiments, a comb-like distribution of transmission resources refers to the transmission resources being arranged or distributed at equal intervals on a time-domain symbol. In some embodiments, a set of comb-like resources corresponds to a set of equally spaced subcarriers or resource elements on a time-domain symbol. In some embodiments, the first transmission resource includes multiple time-domain symbols, and on each time-domain symbol, the resources used to transmit the first indication information are arranged in a comb-like pattern, with different frequency domain offsets corresponding to the resources used to map the first indication information on different time-domain symbols.

[0467] In some embodiments, the comb tooth size is determined based on the spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource. Two adjacent transmission resources refer to two transmission resources that are adjacent in frequency domain location on an OFDM symbol. The comb tooth offset is used to indicate the frequency domain offset corresponding to the comb tooth resource occupied when the first indication information is mapped on the first transmission resource. If the first indication information is mapped to multiple time domain symbols on the first transmission resource, the frequency domain offset corresponds to the frequency domain offset on the first time domain symbol among the multiple time domain symbols. Optionally, the spacing includes a subcarrier spacing or a resource element spacing. The comb tooth size is determined based on the subcarrier spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource, or the comb tooth size is determined based on the resource element spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource. In some embodiments, a resource element can be understood as a frequency domain element, and the resource element spacing can be understood as a frequency domain element spacing; for example, a resource element is a subband, and the resource element spacing is a subband spacing. Normally, the first indication information is mapped to the frequency domain resources in a comb-like manner. However, if the first indication information is mapped to the time domain resources in a comb-like manner, the resource unit can be understood as a time domain unit, and the resource unit interval can be understood as the time domain unit interval. This application does not limit this.

[0468] It should be noted that the "comb tooth size" appearing in the embodiments of this application can all be understood as the interval between two adjacent transmission resources used to map the first indication information on a time domain symbol (or the same time domain symbol) in the first transmission resource; when the first transmission resource includes multiple time domain symbols, the "comb tooth offset" can all be understood as the offset of the comb tooth resource occupied when the first indication information is mapped on the first time domain symbol in the first transmission resource, which will not be elaborated further below.

[0469] For example, referring to Figure 7, the first transmission resource includes one OFDM symbol with 36 corresponding resource units in the frequency domain. The subcarrier spacing or resource unit spacing between two adjacent transmission resources used for mapping the first indication information is 4, that is, the comb tooth size is 4. As shown in Figure 7(a), one of every four subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the first subcarrier or the first resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 0. As shown in Figure 7(b), one of every four subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the second subcarrier or the second resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 1. As shown in Figure 7(c), one of every four subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the third subcarrier or the third resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 2. As shown in Figure 7(d), one of every four subcarriers or resource units is used for resource mapping. The first indication information is mapped to the fourth subcarrier or the fourth resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb offset of 3.

[0470] For example, referring to Figure 8, in Figures (a) and (b), the first transmission resource includes one OFDM symbol, with 36 resource units in the frequency domain. The subcarrier spacing or resource unit spacing between two adjacent transmission resources used to map the first indication information is 2, that is, the comb tooth size is 2. As shown in Figure 8(a), one of every two subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the first subcarrier or the first resource unit of the first transmission resource, with a comb tooth offset of 0. As shown in Figure 8(b), one of every two subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the second subcarrier or the second resource unit of the first transmission resource, with a comb tooth offset of 1. In Figure 8(c), the first transmission resource includes two OFDM symbols, with 36 resource units in the frequency domain. All the transmission resources with diagonal lines in the figure constitute one comb tooth resource, and all the white transmission resources constitute another comb tooth resource. The comb resources corresponding to the first indication information include resources on the first OFDM symbol and resources on the second OFDM symbol. On each OFDM symbol, the subcarrier spacing or resource element spacing between two adjacent transmission resources used to map the first indication information is 2, that is, the comb size is 2. On the first OFDM symbol, the first indication information is mapped starting from the first subcarrier or the first resource element; on the second OFDM symbol, the first indication information is mapped starting from the second subcarrier or the second resource element. The comb offset corresponding to the comb resources used to map the first indication information is determined based on the frequency domain offset on the first OFDM symbol, that is, the comb offset is 0.

[0471] For example, referring to Figure 9, the first transmission resource includes one OFDM symbol with 36 corresponding resource elements in the frequency domain. The subcarrier spacing or resource element spacing between two adjacent transmission resources used to map the first indication information is 1, that is, the comb tooth size is 1. As shown in Figure 9, each subcarrier or resource element is used for resource mapping, and the first indication information is mapped to each subcarrier or each resource element of the comb tooth resource, with a comb tooth offset of 0.

[0472] In some embodiments, the first information associated with the first indication information is used to indicate transmission information on the second transmission resource. Optionally, the transmission information on the second transmission resource includes at least one of the following:

[0473] • The content transmitted in the second transmission resource;

[0474] • Transmission parameters corresponding to the transmission content in the second transmission resource;

[0475] • The location of transmission resources within the second transmission resource; transmission resources are the resources occupied by the transmission content within the second transmission resource.

[0476] In some embodiments, the first information includes the comb tooth size, which is used to indicate transmission information on the second transmission resource. For example, the comb tooth size is used to indicate at least one of the transmission content in the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0477] In some embodiments, the first information includes a comb tooth offset, which is used to indicate transmission information on the second transmission resource. For example, the comb tooth offset is used to indicate at least one of the transmission content in the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0478] In some embodiments, the first information includes comb tooth size and comb tooth offset, and the combination of comb tooth size and comb tooth offset is used to indicate transmission information on the second transmission resource. For example, the combination of comb tooth size and comb tooth offset is used to indicate at least one of transmission content in the second transmission resource, transmission parameters corresponding to the transmission content in the second transmission resource, and resource location of the transmission resource in the second transmission resource.

[0479] In some embodiments, the first indication information and the first information associated with the first indication information jointly indicate the transmission information on the second transmission resource, or, in other words, the first indication information and the first information associated with the first indication information jointly indicate the transmission information on the second transmission resource. Optionally, the first information associated with the first indication information indicates a first portion of the transmission information, and the first indication information is used to indicate a second portion of the transmission information. For example, the first information indicates the transmission parameters corresponding to the transmission content in the second transmission resource, and the first indication information indicates the transmission content in the second transmission resource. The first information indicates the resource location of the transmission resource in the second transmission resource, and the first indication information indicates the transmission content in the second transmission resource and / or the transmission parameters corresponding to the transmission content in the second transmission resource. This application does not limit this.

[0480] In some embodiments, before acquiring the first indication information on the first transmission resource, the acquisition module 1310 also receives configuration information sent by the network device. This can also be understood as the acquisition module 1310 acquiring the configuration information sent by the network device. Optionally, the configuration information is used to configure an association relationship between the first transmission resource and the second transmission resource. This association relationship can also be called a correspondence relationship.

[0481] Optionally, the first transmission resource and the second transmission resource are associated, including at least one of the following: the first transmission resource and the second transmission resource have a one-to-one relationship; the first transmission resource and the second transmission resource have a one-to-many relationship; the first transmission resource and the second transmission resource have a many-to-one relationship; the first transmission resource and the second transmission resource have a many-to-many relationship.

[0482] In some embodiments, the first transmission resource and the second transmission resource are associated. Optionally, the association between the second transmission resource and the first transmission resource is reflected in at least one of the following: the location of the second transmission resource is determined based on the location of the first transmission resource; or, there is a predefined relationship between the locations of the second transmission resource and the first transmission resource based on a communication protocol; or, there is a pre-configured relationship between the locations of the second transmission resource and the first transmission resource based on a network.

[0483] The details of the first information transmitted on the first transmission resource, and the details of the transmission information on the second transmission resource based on the first information, can be found in the section "Next, based on the embodiments shown in Figures 6 and 10, the first information associated with the first indication information will be further introduced." These details will not be repeated here.

[0484] In summary, the method provided in this application involves an information indicating device acquiring first indicating information on a first transmission resource configured in a network device. The first information associated with the first indicating information is used to indicate transmission information on a second transmission resource. This first information is related information mapped from the first indicating information to the first transmission resource using a comb-like mapping method. For example, the first information is the comb tooth size; comb tooth size 1 can indicate one type of transmission information, and comb tooth size 2 can indicate another type of transmission information. This method of dynamically indicating transmission information on the second transmission resource through different comb tooth mappings can improve the flexibility of the communication system, thereby improving resource utilization and transmission efficiency.

[0485] Figure 23 shows a structural block diagram of an information indication device provided in an exemplary embodiment of this application. This information indication device can be implemented as a network device, or as part of a network device, through software, hardware, or a combination of both. The information indication configuration device includes a transmitting module 1410.

[0486] The sending module 1410 is used to send first indication information on the first transmission resource, and the first information associated with the first indication information is used to indicate the transmission information on the second transmission resource.

[0487] The first transmission resource and the second transmission resource are transmission resources configured by the sending module 1410 for the terminal device. Optionally, the transmission resources include, but are not limited to, resources in at least one dimension of time domain resources, frequency domain resources, code domain resources, and spatial domain resources.

[0488] In some embodiments, the sending module 1410 sends first indication information on the first transmission resource. This can also be understood as the sending module 1410 transmitting the first indication information on the first transmission resource, or sending the first indication information through the first transmission resource. Optionally, the first transmission resource is used to transmit the first indication information, which is carried based on a sequence or information bits. The first information associated with the first indication information is used to indicate transmission information on the second transmission resource. Optionally, the second transmission resource is used for downlink transmission, and the second transmission resource is used to transmit DCI and / or downlink data.

[0489] In some embodiments, the first information is related information that the first indication information is mapped onto the first transmission resource in a comb-like manner. Optionally, the first information includes at least one of comb size and comb offset. For example, the first information includes comb size, or the first information includes comb offset, or the first information includes both comb size and comb offset. The resources for transmitting the first indication information are arranged in a comb-like pattern within the first transmission resource. The first transmission resource can be considered as a set of comb-like resources, or a set of transmission resources arranged in a comb-like pattern, or a set of equally spaced transmission resources, or the first transmission resource corresponds to a frequency-continuous resource, and the resources for transmitting the first indication information are distributed in a comb-like pattern within the first transmission resource.

[0490] In some embodiments, a set of comb-shaped resources corresponds to a set of equally spaced subcarriers or resource elements on a time-domain symbol. In some embodiments, the first transmission resource includes multiple time-domain symbols, and on each time-domain symbol, the resources for transmitting the first indication information are arranged in a comb-like pattern, with different frequency-domain offsets corresponding to the resources for mapping the first indication information on different time-domain symbols.

[0491] In some embodiments, the comb tooth size is determined based on the spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource. The comb tooth offset indicates the frequency domain offset corresponding to the comb tooth resource occupied when the first indication information is mapped on the first OFDM symbol in the first transmission resource. Optionally, the offset is based on the offset of the first subcarrier used for mapping the first indication information on the first OFDM symbol in the first transmission resource relative to the first subcarrier of the PRB containing that subcarrier. Optionally, the spacing includes a subcarrier spacing or a resource element spacing. Optionally, the offset is represented as the number of subcarriers or the number of resource elements (REs). The comb tooth size is determined based on the subcarrier spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource, or the comb tooth size is determined based on the resource element spacing between two adjacent transmission resources used for mapping the first indication information on an OFDM symbol in the first transmission resource. In some embodiments, a resource element can be understood as a frequency domain element, and the resource element spacing can be understood as a frequency domain element spacing; for example, a resource element is a subband, and the resource element spacing is a subband spacing. Normally, the first indication information is mapped to the frequency domain resources in a comb-like manner. However, if the first indication information is mapped to the time domain resources in a comb-like manner, the resource unit can be understood as a time domain unit, and the resource unit interval can be understood as the time domain unit interval. This application does not limit this.

[0492] For example, referring to Figure 7, the first transmission resource includes one OFDM symbol with 36 corresponding resource units in the frequency domain. The subcarrier spacing or resource unit spacing between two adjacent transmission resources used for mapping the first indication information is 4, that is, the comb tooth size is 4. As shown in Figure 7(a), one of every four subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the first subcarrier or the first resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 0. As shown in Figure 7(b), one of every four subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the second subcarrier or the second resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 1. As shown in Figure 7(c), one of every four subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the third subcarrier or the third resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb tooth offset of 2. As shown in Figure 7(d), one of every four subcarriers or resource units is used for resource mapping. The first indication information is mapped to the fourth subcarrier or the fourth resource unit of the OFDM symbol corresponding to the first transmission resource, with a comb offset of 3.

[0493] For example, referring to Figure 8, in Figures (a) and (b), the first transmission resource includes one OFDM symbol, with 36 resource units in the frequency domain. The subcarrier spacing or resource unit spacing between two adjacent transmission resources used to map the first indication information is 2, that is, the comb tooth size is 2. As shown in Figure 8(a), one of every two subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the first subcarrier or the first resource unit of the first transmission resource, with a comb tooth offset of 0. As shown in Figure 8(b), one of every two subcarriers or resource units is used for resource mapping, and the first indication information is mapped to the second subcarrier or the second resource unit of the first transmission resource, with a comb tooth offset of 1. In Figure 8(c), the first transmission resource includes two OFDM symbols, with 36 resource units in the frequency domain. All the transmission resources with diagonal lines in the figure constitute one comb tooth resource, and all the white transmission resources constitute another comb tooth resource. The comb resources corresponding to the first indication information include resources on the first OFDM symbol and resources on the second OFDM symbol. On each OFDM symbol, the subcarrier spacing or resource element spacing between two adjacent transmission resources used to map the first indication information is 2, that is, the comb size is 2. On the first OFDM symbol, the first indication information is mapped starting from the first subcarrier or the first resource element; on the second OFDM symbol, the first indication information is mapped starting from the second subcarrier or the second resource element. The comb offset corresponding to the comb resources used to map the first indication information is determined based on the frequency domain offset on the first OFDM symbol, that is, the comb offset is 0.

[0494] For example, referring to Figure 9, the first transmission resource includes one OFDM symbol with 36 corresponding resource elements in the frequency domain. The subcarrier spacing or resource element spacing between two adjacent transmission resources used to map the first indication information is 1, that is, the comb tooth size is 1. As shown in Figure 9, each subcarrier or resource element is used for resource mapping, and the first indication information is mapped to each subcarrier or each resource element of the comb tooth resource, with a comb tooth offset of 0.

[0495] In some embodiments, the first information associated with the first indication information is used to indicate transmission information on the second transmission resource. Optionally, the transmission information on the second transmission resource includes at least one of the following:

[0496] • The content transmitted in the second transmission resource;

[0497] • Transmission parameters corresponding to the transmission content in the second transmission resource;

[0498] • The location of transmission resources within the second transmission resource; transmission resources are the resources occupied by the transmission content within the second transmission resource.

[0499] In some embodiments, the first information includes the comb tooth size, which is used to indicate transmission information on the second transmission resource. For example, the comb tooth size is used to indicate at least one of the transmission content in the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0500] In some embodiments, the first information includes a comb tooth offset, which is used to indicate transmission information on the second transmission resource. For example, the comb tooth offset is used to indicate at least one of the transmission content in the second transmission resource, the transmission parameters corresponding to the transmission content in the second transmission resource, and the resource location of the transmission resource in the second transmission resource.

[0501] In some embodiments, the first information includes comb tooth size and comb tooth offset, and the combination of comb tooth size and comb tooth offset is used to indicate transmission information on the second transmission resource. For example, the combination of comb tooth size and comb tooth offset is used to indicate at least one of transmission content in the second transmission resource, transmission parameters corresponding to the transmission content in the second transmission resource, and resource location of the transmission resource in the second transmission resource.

[0502] In some embodiments, the first indication information and the first information associated with the first indication information jointly indicate the transmission information on the second transmission resource, or, in other words, the first indication information and the first information associated with the first indication information jointly indicate the transmission information on the second transmission resource. Optionally, the first information associated with the first indication information indicates a first portion of the transmission information, and the first indication information is used to indicate a second portion of the transmission information. For example, the first information indicates the transmission parameters corresponding to the transmission content in the second transmission resource, and the first indication information indicates the transmission content in the second transmission resource. The first information indicates the resource location of the transmission resource in the second transmission resource, and the first indication information indicates the transmission content in the second transmission resource and / or the transmission parameters corresponding to the transmission content in the second transmission resource. This application does not limit this.

[0503] In some embodiments, before sending the first indication information on the first transmission resource, the sending module 1410 sends configuration information to the terminal device. Optionally, the configuration information is used to configure an association relationship between the first transmission resource and the second transmission resource. This association relationship can also be referred to as a correspondence relationship.
